I bet you're running low on 378 Weatherby Ammo! We can take up a collection and send you some for the Holidays!! Wouldn't want you to be low on your favorite caliber during field mouse season!!

660 lbs x 9 = 5940 x 7000 = 41,580,000 grs of cordite per 9 gun salute. But I think cordite might be a lttle fast in a 378. Smiler

Wbypwr: "A 378 loaded back with low pressure 2208 loads to duplicate 375 has a softer blast than the 375"
I dont see why that should be so. having a much larger case, the 378 requires more of the same powder to acheive the same velocity as the 375, which results in MORE muzzle blast from the same length barrel, not less.
"The low pressure loads result in the bullet being accelarated more gradually"
True, recoil velocity is reduced with SLOWLY ACCELERATING bullets, but recoil impulse is increased when more powder is needed to acheive the same velocity;
Further, while its also true that low pressure rounds are usually low velocity rounds, if two calibers accelerate the same bullet over the same period of time, the recoil velocity will be the same, while the caliber requiring more powder will gnerate more free recoil. Its not the chamber pressure, but the rate of acceleration of the bullet down the barrel that determines recoil velocity (all other factors, eg rifle weight, barrel co-efficient of friction etc being constant.)

Incorrect. The rates of acceleration down the barrel does not determine the momentum of the gun. If a 300 grain bullet with 100 grains of powder develops a muzzle velocity of 3000 f/s then momentum of the rifle (at bullet exit) is equal to the momentum of the bullet and powder. Normally a velocity of one half the muzzle velocity is used for the powder.

However, the way the bullet is accelerated affects the scope. For example, if the muzzle velocity was 3000 f/s and assume a bullet travel of 25 inches and the bullet increased its velocity by 120 f/s for each of barrel travel, then that would be so easy on the scope that it would be like a 22 Hornet.

Think of it like two cars that did the standing the quarter in 15 seconds. One car is a road car where a 15 second quarter is its best effort. The other is a Top Fuel dragster that is just eased of the line and slow but stead rate of acceleration is maintained down the quarter. Under such a scenario the dragster would be going slower in the first part of the quarter.

Likewise, a larger powder charge at lower pressure that gives the same muzzle velocity as a smaller charge at higher pressure....will mean the bullets velocity in the very early part of the barrel travel will be lower. Thus the peak rate of acceleration of the bullet will be lower and hence the peak accelaration of the gun will be lower.

Also, low pressure rounds are not necessarily low velocity rounds. Compare the pressure and velocity of starting loads in a 30/378 to maximum loads in a 308 Winchester.

It is true that 85 grains of 2208 (Varget)doing just under 2700 with 270 grain bullets will have (if all else is equal) more recoil than a 375 doing just under 2700 with 270 grain bullets and using 71 grains of 2208 (Varget). However, whatever difference there is I can't tell and I have used a 375 in a Mark V so stock etc all the same shape and same contour barrel.

Well perhaps when you can stop beating your chest and proclaiming how mighty YOU are shooting the mighty 2 bore ect. And realize this post isn’t abought what recoil You can handle.

“Bill, have you actually tried loading 81.5 grains of H4350 and a 300 grain Barnes X in the 375 H&H. The Winchester 375 brass we get in Australia nust be very thick and have a smaller case capacityâ€
Why yes I have
First I don’t load The Barnes X bullet they are to long. I use the 300gr partition or the Sierra 300gr spbt. The load I posted was with the Sierra. Let me give you a tip on how to make it work. You have to drop the charge in a scale pan then using a funnel pore the powder into the case while holding it against your vibrating case tumbler. All the powder will go into the case leaving it brim full. Now seat the bullet.
By the way I found that the fastest loads in 378 and 375H&H were with H4350. The next best powder for the 378 was Reloder 22, Reloder 15 is not recommended for the 378.

MTM,
First of all you can do the recherché to so you know that I am not making things up as I go along like some people on hear. The biggest difference in max loads I could find on any reloading site was 300 fps between max loads in the H&H verses the 378 using 300gr bullets. Now if you have done much shooting using a chronograph you will know that not all 378s will do 2950 with a given load (by the way did you know the 375 Remington Ultra Mag does this to, so much for the shrine of The great ROY.) Just like not all 375 H&H rifles will shoot 2650. By the way the H&H is from 24 inch bbl and the 378 is from a 26 inch bbl.
If you are not using a good coronagraph you are just guessing. Just as a disclaimer I did use Published data for this comparison.

Bill just humor and not directed at anyone in particular!! The 378 is, of course, overkill at 100 yards. It shines on big stuff out past 300! I think everyone here knows that. Big Grin

It sounds like you had no choice Big Grin

Hey Billy, look at Saeeds data on 375 Lazzeroni. He was at 3150 with 300 grainers and the Lazzeroni case is just a tad smaller than the 378. Saeed must be bullshitting. I think he took that load to Africa.

Bill, O.K. I just reread the original post. Under 100 yds. the 378 may not be needed. Just for your info. I've reloaded and chronoed several 375s, anything over 2600 is gravy. Granted I've only loaded and chronoed 1 378. I'm just starting on my second. With the first I found it no problem at all to reach 3000 with no pressure signs, I only fired those loads with the same case a couple of times but primers were as new. I think a good comparison would be the 30-06 and 300 WBY. The 06 is fine for most everything, the 300 is a little better.

You make some interesting points, wbypower. However:
"I said the blast was softer"
I cannot tell the difference between soft and hard(?) muzzle blasts, just more or less. Muzzle blast is somewhat subjective, and doesnt have anything to do with muzzle velocity or momentum. It is largely a function of muzzle pressure and the length of the barrel, assuming no muzzle brakes. Overbore cartridges tend to produce more muzzle blast than more efficient certridges, all else being equal, because they burn more powder to achieve the same muzzle velocity
With regard to your sports car analogy, you may have something there, i admit; I am not nough of a ballistician to say for sure.
BUT many AR double rifle shooters will attest to the fact that with a 470, eg, the recoil is more of a had shove than the sharp punch of a 378 Weatherby, even though the powders geberally used for these are relatively fast, eg IMR3031, to duplicate the original cordite loads.
Perhaps a pro ballistician should weigh in?

Indlovu,

Perhaps a better description is to say the muzzle blast is a lower pitch.

These days my ears are sensitive to blast and for me the use of a larger case loaded back to equal the maximum ballistics obtainable from a small case results in "less or softer blast"

However, the bottom line is that a 378 simply offers the reloader more than a 375. The 378 certainly has the disadvantage of being limited to the Mark V or CZ (aside from expensive custom actions) but that problem can be overcome if the 375 RUM is used.

You are right MTM but we both know that a different .378 might blow primers at 2950. The difference in chamber barrel barrel free bore ect.can make a big difference in what works in 1 rifle and not in another. beer

WbyPower,
The 9.53 SATURN is not a round I have any experience with. I don’t know what the case capacity is nor do you or you would have posted it. I wonder what the pressure was.
If Saeeds has published it I believe him.
But what is your point?
“Bill, you need to stick to double rifles, tradition and a stop watchâ€
You are absolutely right. Punching holes in things with .577 NE is much more satisfying than using a wimpy bb gun like the .378 Wby. jumping

Bill,

The bigger Lazzeronis are a tad smaller than 416 Rigby head diameter and Lazzeroni told me that was to prevent people making the brass from 416 Rigby.

So Saeed's velocities were with a 375 using a slightly smaller case than the 378.

As a side note, since you shoot a 577 Nitro then any anti 378 arguments based on recoil would not be relevant to you Big Grin

I like big bangs simple!! .. and can load up and down .. and if i happen to burn through a few Kg's of smokeless at the range ... well I am keeping the industry healthy!

The best caliber .. is the one u like to shoot and shoot well!

I have a 375 Wea. I feel left out or perhaps obsolete.
I can hit what I shoot at with it. I think that is what is most important along with good projectiles.
2800 FPS (factory loads; 300 NP's) out of a semi custom Mod 70; Chronographed. It may be a bit fast but it seems very flexible for almost any application and I can get 4 cartridges in my drop box mag to boot. I can shoot 375 H&H's through it if required.

Your thoughts?


Well, you know guys, talking about the .378 Wea and Peter Chapstick, it seems it and he are either loved or hated and many times for invalid reasons and no personal knowledge to back it up. I am old .378 user, for the most part liked it, big recoil, noisey kills like they have been "sledge hammered.". Generally. To me bullet failure is when it fails to kill with a proper hit. Never had that happen. I read PHC when he put the books out and he had no influence on me as was there doing it at same
time period he was there in Africa.
The closest I ever came to bullet failure would have been on a timber wolf ,near Chetywnd, B. C., 100 yards, broadside, 300 grain Silvertip loaded full up. It didn't exit broken shoulders, we found fragments under the skin. Now had that been a cape buff or a big eland, it might have been "bullet failure". I took it on my first trip to Tanzania and the PH had never seen one, but was impressed with the kills and didn't complain about the muzzle break noise, said he'd be recommending it. Anyway I went away from it and had Tom Burgess put a .416 Rigby barrel on it.
Now, a word about the safety complaints. I never had any, put a Canjar trigger in as part of change over, never had a problem. I have read about guys hauling around in the truck all day, LOADED, and they went off when they took the safety off to unload it or use it. Well guys, I wasn't born yesterday, but if the guy was in that position and the PH agreed to loaded rifles in the truck, then I am willing to bet dollars to dounuts (that might be about even in today's world!) that they were hunting and SHOOTING from the truck. If you don't have time to chamber a round as you move away from the vehicle, then something is wrong in that pictures of the ethics I am seeing. Then I've seen that complaint with sone Roy built in the early years on FN MAUSERS. If that is true, why don't we hear the complaint on FNs and early Sakos in .270, .30-06, .300 H&H, .220 Swift and so on? Same darn defective SAFETY!
I've been sorely tempted to buy another .378. Ain't got any need for it, but it's set up right, G&H mount, 2 3/4 scope (oh!, yeah it's a worthless Weatherby also!)and to top it off the barrel has the Pendleton muzzle break built in. (No ugly screw on!) With today"s Swifts, Barnes and Hornady DGS, I am not afraid to give it a whirl. I don't think it's the "all things to all People" that Roy promoted it to be when it was new for Dangerous Game, but for heavy mountain and heavy plains game, and up to long ranges too, if your into that sort of thing. If you cannot handle it or its not "your cup of tea," then leave it alone and stay away from it.

Same thing with PHC, if you cannot stand the fact he may have lied or embellished to make a story, then don't buy his books. As I have said, I have his books, they don't do much for me. Maybe, if I am still here in 15-20 years they will light a spark and maybe not.

I got my spark from Taylor, O,Connor, Keith, Herb Klein, Hibben, Warren Page, Ruark, Hemmingway and guys like that, that wrote while PHC was still selling stock and sticking pigs with a knife or whatever. Do you think there was never anything except fact in their stories and books? I doubt it. They had to make a story our of a few seconds on the sight picture!

Have a good day, some of the "tear down" podstings are funny when viewed from a sideline.

According to Weatherby advertizing, they actually killed three cape buffalo with one shot!

Today those folks might be using softs such as A-Frames or Northforks or triple-X and reduced penetration a bunch.

Why the 378,

I own 1 375 H&H, and 2 9.3x62's and I love them both, but my 378 is hell on wheels. It shoot futher, hits harder and is very accurate.

I'm in the process of building a lefty in a 378, on a left hand Mark V.

I'm going to put a 1-10 twist barrel on my new 375, I only shoot 300's out of it anyway.

The only thing I dont like about it is it really needs a muzzle break, or weight. My shultz &larsen is a little light at 9lbs, and my new one will be syn stocked with a 26in barrel. I might just try a break-o in the butt first, but I know I'll end up with one of those damn "noise makers" on the end.

I can't imagine where I would need a 300grn bullet at any where near 3000fps.
And I have a vivid imagination. Wink

300 grain bullets at 3000 fps comes in handy if your hunting skills are lacking and you can't get any closer than 500 yds from your elk; and/or you're compensating for some other anatomical shortcoming. Big Grin

This is an interesting thread – reminds of a bunch of kids arguing which car is best for getting to work. Some like Toyotas, some Volkswagens, some Corvettes, some Cadillacs, some Hummers, some old clunkers, etc. They all work – it’s just how they make you feel while you go into work. I always laugh when I see someone on the super highway in a super-raised 4x4 truck with massive tires and 400+ cubic inch engine – he’s probably never had it off road. In fact, I’ve been told by car dealers that most 4x4s have never been off road.

We buy 378 Weatherbys because we can, not because we need them. Although I don’t own one, I do have a 375 Ackley Improved (26” barrel) that I load to the max – it’ll produce 2935 fps with 300 grain bullets using Norma MRP. It’s all I can handle, it’s a 600 yard weapon, and I can’t imagine anything standing after a hit in the boiler room – BUT, I’ve not killed a damn thing with it – at least not yet. I am planning a hunt to Africa, and it’ll be the only gun I take. The hunt will include Cape buffalo and a number of plains game, the latter of which could be killed just as easily by a 30-06. I just don’t want to take two guns – then two might get lost or stolen.

Why should 90% of the cartridges on the market exist? Overwhelmingly, they are redundant, since we could all probably get along perfectly with 10 centerfire cartridges or fewer.

.221 Fireball
.22-250
6.5x55
.30-06
.338 WM
.416 (Rig, Rug, Rem)

There, I stopped at six. We can dump all the others now.

The .378 Weatherby exists because it scratches an imaginary itch, just like all the other cartridges that aren't on my magic list of six.

Besides, it just looks cool.

The ultimate .375. No gain on big game within 100m. Massive gain at 600m on big game.

OK .. but now for a serious Question !!!

Who has some once fired brass to donate to me?? here in SA we are paying almost $3.5 for new brass. I wont even go into what factory Ammo costs !!!

and this is not .. an oopportunity for the H&H boys to make jokes about ammo prices .. its a small price to pay for such a fine caliber( its the powder that gets pricy ..LOL)


I just like things that go BANG!!!

I've owned rifles in 375H&H, the 375Wby, 375 Ultra and even spent some time with a buddy's 378.

Bottom line is I like them all....The 378 not so much, but that was more of a personal dislike for the rifle's short pistol grip, goofy comb, and a bolt handle way too close to my knuckles (no offense to the Wby fans). My opinion is that the 378 gets its vicious reputation from the rifle design.

The 375H&H is the 30-06 of medium bores...If you like the 30-06 you'll like the old H&H.....Not a bad comparison...Both are great.

Of all the 375s my favorites are the 375Wby and the 375 Ultra.

I like the Wby because it is easy to get good velocity from (feed it almost any powder), has modest recoil, and it had a bit more power than the H&H with no apparent down side.

I like the the Ultra because it is a hot rod that gives me no reason to shoot anything less than 300grain bullets....I like it for long range moose.
It works very (VERY) well.

I would probably shoot the 378 if it was chambered in a rifle I liked.

In other words, IMHO, the .378 is the wrong caliber for its mammoth sized case.

I have taken an Australian buf.and a Cape buf. with the 378-as well as donkeys and horses-I have used a 416 Rem,416 Rigby and 500 Nitro in Africa.The 378 is a bastard of a gun to shoot and yes the PH's all hate it,but with solids it would shoot through anything I pointed it at.
I prefer the 416 Rigby in a bolt but they are all inferior to a 500 Nitro.


Australia
I love a sunburnt country,
A land of sweeping plains,
Of ragged mountain ranges,
Of drought and flooding rains.
I love her far horizons,
I love her jewel-sea,
Her beauty and her terror
The wide brown land for me!

Though many do consider the 375 adequate for cape buff I happen to agree with mrlexma

As a kudu, elk, bear, moose cartridge a fast 375 (with modern bullet) is pretty much without peer in ranging/killing power..Whether you need all that rang/power is another story.

The fast 375s do seem to put game down North American game with more authority than the H&H and seem to kill just like a 416 does. That said I do not think the extra damage caused by the velocity of a 378 will impress a buff any more than the standard 375H&H...Just too much tough animal there!

coffee A couple years ago, I was at our range with a friend when he mentioned he was taking his father on a black bear hunt in N. Ontario. Since I knew what my friend was shooting (a Marlin in 45-70), I asked what his dad would be using. He said, "His usual that he uses on everything". "What's that?" I asked... "His 378 Weatherby" was the reply in a calm, unexcited voice. Just routine. BTW, his father was 83 yrs at the time! Eeker

As a matter of interest, about three years ago I had an opportunity to purchase a slightly used WBY Mark V in 378. I did a profile on the ballistics and I was mightly impressed! As a flat-shooting cannon nothing touches it!

But, I agree with some other posters who feel that beyond a certain level of velocity, for extra-large game and DG, a larger bore is better. In fact, I'm a .458" guy and chose a CZ in 458WM. It'll shoot a 350gr TSX at 2700fps with ease. That's about as flat as a 30-06, or a 378 with the same weight bullet. Now, I realize those are 458 Lott numbers, but with my true magnum-lenght action and long freebore, it's possible to seat that bullet and crimp in the rear cannelure (same as for all Barnes bullets, including the Banded)so in effect I have a 458 Lott. That makes a pretty flat-shooting cannon too! BOOM

Nothing wrong with owning a .378Wby. Fantastic round that will take anything. All those nay sayers are just jealous because they don't have one Wink
