500 grains,

A big part of the appeal of the 416 Rigby is being able to develop good ballistics at low pressure due to the large case capacity.

Do you deny such benefits to the 375 Wby, 375 Ultra and 378 Wby.

Holy shit, the 378 could probably equal Winchester 375 factory ammo while using black powder.

Mike

Wombat,

Here i you thread which included my reply. I just noticed that when the thread is opened it is holding the bold typing for 378 for which the search was done....Mike

Good and laughable point.

Now why highjack this thread to your own .378 Wby Mark V pet?

With a CZ 550 rechambered to .375 Wby, one gets 5 down and one up the spout for a practical 6-shooter, and one can make his loads +3.75" COL with Walterhogs or equivalent Barnes TSX's of 300 grain weight, crimped where one pleases.

That is way over 30,000 ft.lbs. per reload of rifle.

Mike375,

To clear up any confusion, the things I do not like about the Wby Mark V as a DGR are as follow:

1. Not controllled feed.
2. No iron sights (usually).
3. 9 locking lugs is B.S. I bet only 3 of them make good contact.
4. Not a particularly safe action in the event of a barrel obstruction. Those 9 locking lugs have been known to let go and permit the bolt to travel rearward through the shooter's cheek. Doesn't happen with a Mauser or M70 Classic.
5. Factory loads and publshed ballistics WAY too hot.
6. Stocks too shiny (usually).
7. Monte Carlo.
8. Only 2 rounds in the mag.
9. A lot of Mark V's shoot like crap. But that problem seems to have gotten better lately.
10. The Mark V safety can be rattled into unreliability. Maybe Wby fixed that, I don't know.
11. When the sheet metal feed lips get bent (happens sometimes) forget about the rifle feeding. And YES, it does happen. Ever hear of anyone bending the rails on a Mauser?

However, I don't have a problem with the .378, except when it is loaded too hot. As I said before, it's a great long range big game caliber (so is .375 RUM). I would love to snuggle up to a .378 if shooting at a Gemsbok at 500 yards.

I will make you a deal. If Wby goes back to a M98 action, I will buy one in .378.

NNN,
The issue here is not Craig Boddington. Boddington writes some good stuff along with a lot of bad. KA-CHING.

The issue here is the .375 Weatherby, which you still don't know anything about.

I like Craig Boddington's writing. Magazine writers have to be pretty diplomatic to continue working, but I think it's fairly easy to tell when he is really enthusiastic about a product and when he is "damning it with faint praise".

I'm curious about the fast .375's: do they have a more visible effect on buffalo and other DG? One thing several folks have mentioned is that while the .375H&H will reliably kill a buffalo, it's difficult to see the effect of the shot or even to get an indication of a hit at all, whereas the .416's and bigger have a more noticeable effect. Ray, Saeed, or anybody care to comment?

Steve

NNN,
How do you expect me to discourse in a civil fashion with a liar like you? You repeatedly accuse me of alcoholic delirium when I am a non-drinker.

You posted something about loss of hospital priveleges then edited it out.

Have you been sleuthing the internet and found another Dr. Ron Berry with problems? It is a pretty common name. Those are not my problems.

My problem is that NNN makes up goddam lies about me.

Dan McCarty you are a LIAR. I wouldn't trust you as far as I could throw you, but that would be a pretty fur piece as whimpy as you are.

Now stop your lying. Try to have a more positive outlook on life, and you may redeem yourself.

BTW, just mentioning Boddington sure attracted attention to the .375 Weatherby didn't it? Craig is good for something. It is a tough job he does, walking the tightrope strung up by the publishers and advertisers on one side of the chasm, and all of us on the other side.

There he is the prima donna supreme gunwriter, doing back flips on the tightrope for all to see. Gotta give him credit for something. Maybe even a good laugh now and then or a wink and a nod between the lines.

(Hopefully the last edit on spelling so it is crystal clear.)

RIP,
Does the cz (zkk 602 in my case) require any modification to the magazine box because of the change in cartridge taper when going from H&H to Weatherby?

Six months ago I couldn't even spell 375 Wetherbee, and now I own a reamer and a rifle.

A CZ 550 Magnum with a plain wood stock in 375 WBY is what we call a stealth Weatherby in my county. The elk think that puny 375 H&H bullet won't reach out that far and the next second "WHAM", and their lungs are forty yards further up the hill.

lawndart

One thing I've found with the .375 Weatherby is that it kicks like an onery mule. If you are going to put up with that kind of abuse you might as well settle on the .416 Remington. Actually, I almost think the 416 is easier to deal with in the recoil department.

JohnAir,
All you gotta do is run the reamer into the chamber, then polish up the feed ramp and bottom sides and edges of the feed rails and any surfaces of the follower, and any breech surfaces that bullet and brass slide by should be polished smooth, just do the things that CZ should have done to their .375 H&H. Then you have a slick feeding .375 Wby, 5 down plus one in the chamber. a careful polishing of boltface and extractor edges wouldn't hurt either. Just make it smoother like you should for the .375 H&H anyway. Glass bed the walnut stock, and I added crossbolts fore and aft of the magazine well. It is the easiest conversion in the world, and converts to the world's best cartridge.

Does the lee factory crimp die for the H&H work on the Weatherby?

I´m sold on it. I was looking for just such a set up, 2700 or over for 300 gn barnes banded flat nosed solid and the ability to shoot .375 H&H make it pretty attractive.

lawndart

lawndart,
Cool! Stealth Whether-be.

All you have to do is stamp "WBY" after the ".375 H&H" on the barrel. Could be the only giveaway to casual inspection, but this could be omitted for black ops purposes.

500 Grains

1. Not controllled feed. I regard that as a positive and especially when combine iwth in line feed.
2. No iron sights (usually). You are big on a gunsmith checking a rifle. Wby has an array of pre packaged custom guns, Product Upgrade, Bulding a Custom Gun that soon takes care of the iron sight situation.
3. 9 locking lugs is B.S. I bet only 3 of them make good contact. They musy be good steal when people keep saying Mausers will set ack if used continually with high pressure loads in the 404 Jeffery, a smaller case head than the 378 calibres.

But the 9 little lugs serve another purpose. When a Wby bolt is closed the two lower sets of lugs are at the 4 O'Clock and 8 O'Clock position and this allows a Weatherby to have a very long magazine in relation to receiver length. The little lugs also mean the inside of the receiver is not cut away by two big locking lug recesses.
4. Not a particularly safe action in the event of a barrel obstruction. Those 9 locking lugs have been known to let go and permit the bolt to travel rearward through the shooter's cheek. Doesn't happen with a Mauser or M70 Classic.

After careful examination even Ken Howell said the event was dodgy. The bolt handle would have had to have sheared off for the bolt to go through the shooters cheek. Remember a Wby is an a one piece bolt. Of all the actions about the place and in combination with the chamberings, notably 30/378 available in the cheap Synthetic action they would be the most thrashed action out there and should be falling appart everywhere. By the way I have personally fired a 378 where the powder measure was set for maz loads with IMR 4350 and 270 grain Hornadys but the measure was used with Varget. A near as we could tell by using fired cases fired on the same day there appeared to be perhaps a .001" or less set back in the action. I did not realise what happened until I went to open the bolt.

5. Factory loads and publshed ballistics WAY too hot. The majority of 300 Wby ammo I have chronographed has been in the 3150 to 3180 area, fully 100 f/s under what it can be easily loaded to. 378 ammo typically chronographs at the 3080 mark with 270 grain bullets, again, fully 100 f/s under what you can load to.

6. Stocks too shiny (usually). Again you have an options list.

7. Monte Carlo. Personal preference. many shooters, myself included find both recoil and quick shouldering of the rifle is best served by a stock where the centre of the butt is well below the axis of the bore. The monte carlo is to make such stocks suitable for scope use.

Lazzeroni use an almost identical stock shape. I am not using Lazzeroni as endorsement but just to illustrate we are in person preference area. We have a high grade glass stock maker in Australia who makes the Wby style and the American classic style and he recommends the Wby style for the big bangers, of which he does many because of the CZs.

8. Only 2 rounds in the mag. Again the options list and you can have 3 in the magazine. Also rememeber the the in line Wby can be loaded into the magazine while the bolt is closed on a round. I know you can si the same with a staggered feed but the feeding reliability can be and often is stuffed and doubly so if a CRF.

9. A lot of Mark V's shoot like crap. But that problem seems to have gotten better lately. Partly agree. Some were very bad in the 1970s. The combination of feebore diameter being too large, long thin barrels that were not good barrel and being shot to over heating.

10. The Mark V safety can be rattled into unreliability. Maybe Wby fixed that, I don't know. Don't know as I don't use a safety. But the following might be of consideration. Wbys in general are highly regarded in Australia where we do far more shooting than any other place and we do it from the vehichle and rifles spend a lot of time in the heat, dust and vehicle. A full nights spotlight shooting and the land cruiser needs to be refueled for the next night. As a side note, Rem 700s are highly regarded in Australia as well.

11. When the sheet metal feed lips get bent (happens sometimes) forget about the rifle feeding. And YES, it does happen. Ever hear of anyone bending the rails on a Mauser?

I have never seen that happen on a Wby and find it strange that it would as they are very heavy. But if does, then buy a spare magazine box because a Wby only depends on the magazine box for feeding, action rails play no part. A similar rifle was and is the 303 SMLE.

Try chasing roos and pigs with a 303 SMLE and a Mauser and you will see that the Brits learnt the limitations of the Mauser and so went in another direction.

However, I don't have a problem with the .378, except when it is loaded too hot. As I said before, it's a great long range big game caliber (so is .375 RUM). I would love to snuggle up to a .378 if shooting at a Gemsbok at 500 yards.

I will make you a deal. If Wby goes back to a M98 action, I will buy one in .378

Sometimes they are for sale on GunsAmerica or get Empire to one for you as they chamber all the Wbys and you save $2000US by not using the Granite. The only calibre they list where the Granite is required is the 505 and that is obviously the .75" bolt diameter option on the Granite.

I also notice that what Empire call their Flagship rifle is not on the Granite so I assume the other Mauser they are using are good.

By the way, in your listing of Wby faults you actually left out the main (and true) faults associated with the Wby action and in particular those associated with the 9 lugs. Would you like me to list the faults for you.

I don't know the answer to that, but they are the same length at the mouth of the cartridge. I suspect that the blown out .375 Weatherby shoulder might prevent it unless the Lee Crimp die is just a short neck and roomy below that. Let us know if you find out. I need one if so.

Steve

Saeed seems to have settled on about the 2750 number for 300 grainers. He has used the 375 Lazzeroni, which is essentially the 378 Wby, at 3140 with 300 grains Barnes X and has had his 375/404 at over 2800 and has expressed the opinion mnay times that about 2700-2750 or so is the number.

In essence, Saeed is using a pair of 375 Ultras that are loaded to 375 Wby ballistics. He has also said many times that the H&H does as well but the trajectory is not as good for all round shooting and I think that would be a reasonable comment because a 375 H&H would be battling to get out of the mid 2400s with the long 300 grain Barnes X bullets unless helped along by a Chrony

Mike

I will. Thanks for the great idea and the info. It´ll be awhile till I get the reamer down here but I´ll be sure to post something when it gets done.

When I was interviewing at various units before going back in to the Army (reserve) I found out that some Spec Ops units allow individual members to take a POW (privately owned weapon) over to the the spec ops theme park (southwest asia). I was like, "Way cool dude, I'll bring my 375 Weatherby for self defense as a medic/doctor type!" The recruiter guy said "Put your pecker back in your pocket dude; you have your choice of 9mm, 45 ACP, 5.56 or 7.62". Man, was I bummed.

lawndart

You have to send a dummy round to Lee with $25.00 for the 375 Weatherby case. Two weeks turn around time. Well worth it.

lawndart

There has got to be a country song somewhere in Rip and 500's relationship.

Rip,
You can borrow my new reamer (PT&G) any time.

To Weatherby, or not to Weatherby -- that is the question.

Or to take ideas to a single idiot ...
Aye, there's the rub!

Nevermore.

Can you put that to music lawndart? And thanks for reminding me of the Lee Factory Crimp Die custom procedure.

My smith has a Dave Manson reamer for my next .375 Weatherby project. So far it has only cut two chambers for me. There may be more.

A certain person is persona non grata in my book now. Watch your back if you go out to eat in Salt Lake City.

Mike

Mike I may be missing something but I just went down to my buddys house and his .338RUM is definatley a staggered magazine. It is in no way shape or form an in line vertical magazine. The .375RUM is identical as far as I know. If I am not mistaken the Mark V's are staggered as well? I've got one right here a .270WBY Mark V no doubt about it staggered feed?

Am I missing a key concept here?

Greg

500,

The first problem is poor primary extraction and with tired brass you will finish with the bolt handle open and then have to tap it back.

The second problem is caused by the original design for an action that would take all Rem 700 mounts. They have a deep recoil lug like an M70 but the short bedding platform means the screw goes into the recoil lug like a Mauser. Apart from the superior bedding configuration offered by the screw bing in the centre of the bedding platform, the deep recoil lug on the Mark V means the thickness of the stock material between the floor plate and bottom of the recoil lug is very small.

Sometimes when someone assembles the H&H based Wby, like a Rem 700 they get the magazine bound and the floor plate bends and digs into the wood. Compounding the problem is the narrow metal at the front screw end. Because the wood is so thin between the bottom of the recoil lug and the floor plate it is hard to do some with a pillar. On the hand, a Rem 700 is simple. I simply drill the hole out and then cut out the stock bedding area and a shell holder becomes the perfect pillar with the floor plate resting on the small end of the shell holder.

The Wby action also rips the shit out of cases. Part of the problem is that in the bolt open position one row of locking lugs is at the bottom and drags across the belts and cases.

This problem is increased because Wbys need srong magazine springs to feed because of the bolt nose protruding beyond the lugs. The lugs depress the case below the bolt nose. If you have very fast hands and the spring bias is weak at the back you can move the bolt backwards then forwards fast enough to be the case head rising high enough for the bolt nose to engage it. Actually, the Mark V effectively turns every cartridge into a rebated rim.

However, I have never seen anyone be able to do this when the rifle is actually being fired. In other words, if I change the bias on the spring I will jam a 378 everytime for you while in the lounge room, but not while firing.

On a positive side, I think the are the fastest action to use provided the person is use to using them all the time. The short bolt lift tends to prodice a whole hand grabbing the bolt and the very heavy bolt seems to produce a flywheel effect.

Some more negatives. Because of the big bolt diameter and Rem 700 receiver size the metal in the rear receiver ring is really to thin to go to the larger 8 X 40 screws. Personally, with glued and screwed based I have never needed more than the standard 6 X 48 but if I did want the bigger screws then the Mark V would not be the ideal candidate.

The combination of the big bolt and Rem 700 size receiver also means the number of threads in the tang is small. More than adequate but wen bedding Wbys you have to make sure the tang does not finish a bit higher than original. In some ways they would be a little better if they had the small square section a Model 70 adds to the tang but then again that complicates bedding as you need clearance behind that square section

For those where trigger over travel is an issue, which it is not for me, then the Wby is always limited because the trigger has to be able to be pulled far enough back to work the bolt release.

On a positive with the trigger, it is adjustable for weight of pull and sear engagement without pulling the rifle apart. With a lighter trigger return spring as opposed to those fitted to Wbys for the last several years, they will virtually all adjust down to a 1 pound pull that is reliable. Some will come down to half a pound.

Another negative is the firing pin is indexed by a ball and if someone screws out the firing pin the ball will fall out and they will notice. They assemble the rifle and then can have ignition problems. This can lead to overloads because the loads are showing normal pressure but in reality are too high and then the next load goes off properly. I have never understood this with primers as you would think they either go off or they do not go off. Don't know about current Rugers but they use to use a weak firing pin spring.....I guess to make the rifle feel better in the gunshop....some would misfire and Rugers would often give lower velocity but it went up when a new spring went in.

Another problem with the 9 lug set up is that they do not make for a good switch barrel rifle due to action wrench problems. But they are also poor candidates because of the position of the front screw and they really need bedding under the half inch or so of the barrel.

The freebore, which of course is not action related is in my opinion a mixed blessing. If it the freebore diamter is OK they will shoot right up to the potential of the barrel. They also suffer less from pressure spikes and are also more inclined to shoot loads from different barrel fouling condition into or right next to the group. However, they are in general (in my opinion and experience) accurate with less loads than a conventional chamber. However, they will usually give higher velocities with powders that would be considered to fast for the calibre.

I have had quite a bit to do with 460s and when bedded and floated I think they must be about the most accurate big bore out there. I have used the 378 and 416 extensively and the 416 does not have the long freebore of the 378 and 460. Believe it or not, but a 378 with 270 Hornadys seated to the cannelure has a .8" run to the rifling and the 460 is similar with the 500 grain Hornady. But I have never been able to get the 416 with its best loads to equal the accuracy of either the 378 or 460. Quite some time ago I was talking to someone in HS Precision and his feeling based on Wby chamberings (which they do and with their accuracy guarantee) was that with the right load freebore seemed to give the best accuracy. I have a couple of theories of "why" but that is for another thread for another day.

One last fault which is economic is that as soon as you do anything with them such as Product Upgrade the cost goes way up as they no longer offer the same deal to dealers or importers. But the rifle is better.

Mike

Greg

The Rem 700 African Big Game Rifle is centre line feed. Of course for the other the Rem 700s you can buy the HS Precision in line feed magazine.

Wbys are all staggered feed for the small H&H based calibres but not for any of the 378 based calibres from the 30/378 through to 460. The little 224 was also centre line feed.

I will get a 416 Wby and load 400 grain Hornadys backwards and back it against ANY stagger feed rifle and doubly so if the staggered feed is a 416 Rem. The reason I mentioned the 416 Rem is that that the bullet diameter is much closer to the chamber diamter than is the case for the Wby/Rigby

Mike

This must be one of the longest running threads for a factory calibre of such limited popularity.

It would be interesting to see what would happen if Winchester introduced a 375 Winchester Magnum (ie. 375 Improved) and released it in their standard non custom shop rifles.

The growing popularity of the long solid copper bullets certainly adds to the 375 Wby/Improved's arsenal.

Mike

Mike,
I wouldn't look to Winchester to do anything that sensible in our lifetime.

They might come out with a 375 on the WSM or WSSM case though.

Who knows, the newer powders and bullets may conspire to boost the popularity of the 375 WBY or its moral equivalent.

lawndart

JohnAir,
If you do a search for Beartoothbullets and go through the Tech Notes, there's info on reloading for the Ackley Improved cartridges. There's talk of using the Lee Collet die to neck-size the 375Ackley Improved, same thing may work on the 375Weatherby. May be useful to keep in mind. Given the same case length, the crimp die should work too.
Cheers...
Con

lawndart

You can bet your balls (both of them ) that Wby will not promote the 375 Wby. Too easy to buy those Winchester 375 cases. Thats why the brass is 378 type pricing instead of 300 and 340 type pricing. They probably know that a lot of people with a M70 375 Wby rechamber would like at least one or two boxes of headstamped brass and since only a box or two then they will pay 378 type prices.

They do some of them in the custom shop where someone wants the match up with the 300 Wby whereas the 30/378 bloke goes 378 Wby.

Mike

Mike375,
Thanks for sticking to the topic, occasionally, as well as beating the surrounding ground nicely. The brass issue is a definite thorn in the .375 Weatherby's paw, and makes it the red-headed stepchild of Weatherby bean counters. No one is promoting the .375 Weatherby except the .375 Weatherby. It is a proud, self-made cartridge.

For the life of me, I see no need for any other rifle anywhere in the world. Take along the .375 Weatherby, and you can leave the .375 H&H at home and fear no evil.

You can always bring along another rifle, smaller bore, bigger bore, or same bore in the form of a .375 H&H. You will always have it all covered, as long as you have the .375 Weatherby along with whatever peashooter or cannon. Or go .375 Weatherby alone.

IIRC, our hero Raymond Johnson in Unintended Consequences had a battery of .375 Wby and .510 Wells. He might have been better served by a .375 Wby plus a .25-06, if there were no call for chest beating images of Bwana.

I tried 6 dummy rounds of .375 Wby in the box of a .458 WinMag CZ 550 American Safari just now. All six will go in the box, but the top round is too tight to feed. It is loose enough to allow the sixth round to be pressed down onto the top of the stack enough to slip under the extractor and CRF on into the chamber.

A different follower could be devised (thinner) that would allow the CZ 550 to hold 6 down plus one in the chamber, the seventh round being loaded directly into the chamber and bolt closed with side-finger-pressure on the extractor. As is 5 cartridges feed beautifully out of the box, and the sixth is easy to CRF off the top of the stack.

A SEVEN SHOOTER .375 Weatherby is getting 300 grainers up to 2800 fps for 6224 ft.lbs. KE X 7 = 43,568 ft.lbs. for each reload of the rifle.

RIP,

You may already know this, but Warren Page was a 375 Wby shooter.

Note: 500 Grains keeps forcing me off topic

If one was to summarise:

1) Saeed has clearly established that the ballistics afforded by the 375 Wby are suitable for shooting all size animals from elephants down to those little antelopes about the size of a small dog. Since he takes a pair of "375 Wby ballistics" to Africa that would indicate he feels no need for anything smaller or bigger, faster or slower.

2) Saeed has also established that ballistics in excess of the 375 Wby are a backwards step, certainly with Barnes X

3) The 375 Wby allows you the convenience of 375 H&H ammo and in addition if you are like 500 grains and believe bullets should go slower then the 375 Wby will slow down 375 H&H ammo by maybe a 100 f/s.

Beautiful,
Yep, I recall Warren Page, and for the famous guide, there was Hal Waugh of Alaska with Big Nan, his faithful Pre-64 M70 rechambered to .375 Wby.

Actually Boddington made a big boo-boo in his piece. He said that the .375 H&H ammo would be slowed down by 300 fps, which is dead wrong. The current .375 Weatherby will slow down factory .375 H&H loads by 125 fps in my rifle.

That makes a classic 300 grain 2530 fps .375 H&H load from the .375 Wby chamber come roaring out the muzzle at nigh onto 2400 fps.

This is the perfect magic number for the slow bullet crowd.

It also makes for less recoil and perfectly fireformed .375 Wby brass. Use Winchester, as you say.

So anybody who flinches with a .375 H&H needs to get a .375 Wby to fire their factory H&H ammo in to gentle it down. Then send the once fired brass to a .375 Wby friend.

And in addition if you can only locate Hornady or Federal High Energy ammo or whatever it is called the 375 Wby chamber will bring that ammo back closer the standard H&H ballistics.

As a by the way, I had a 375 Improved done in the very early 1970s...a rechambered M70, so I was quite an early visitor to the calibre and powder was the issue.

That is funny, can only locate the HE or Heavy Mag stuff. But the Weatherby chamber would definitely be the best place to fire it. That might bring some semblance of accuracy to it.

So you beat me to the .375 Improved by more than a decade, eh? That is cool. And I thank you Aussies for bringing us the Hodgdon Extreme line of powders. H4350 Extreme with 300 grain bullets is all I really need to keep on hand.

Cheers!

That's "Barq" brand of root beer in those mugs! Barq has a bite of caffeine to it.

RIP,

That is the one and only time I have owned a 375 Improved.

I don't know if this applies in the US of A, although the forums suggest it does, an observation I have made out here over the years is that the 375 Wby/Improved is often discussed in very desirable terms but the rechamberings or new made gunsmith rifles do not actually eventuate.

The spirit is willing but the flesh is weak, I reckon.

Since it may take a year for that Dakota 76 African action to come in for building a .375 Whatever, I will not let the Dan Lilja barrel lie fallow.

26" fluted stainless N0.6 contour Dan Lilja on that CZ 550 American Safari Magnum, to become a seven-shooter .375 Wby. Then I am calling it quits until the Dakota action comes to port.

Might as well change my handle to Rip375.

Whats going on a whole page without a fight??? Come on you guys are letting us down.

Is that the waiting time to get a Dakota action.

Yes, you need to change to RIP375

RIP... whats the word on the stainless 76 action? You said they were not making one. Before you had said that... my sources said they were though. whats the word on it?

An alternative to Dakota but big enough for 505 with .75" bolt diameter option.
