Hornady custom dies run only $50--amazing deal actually. You can seat boat tails directly in 338 win brass, some guys will even pull the bullets from cheap 338 factory rounds, replace the powder, seat a light 375 bullet (230 speers for instance) and ust that as a fireforming load). You can apparently get 250's to 2800:
375 Chatfield-Taylor loads

I've heard of people just using a .338 reamer and throating to 375 but don't trust that. Do a search here for mor info...


Great in a shorter barrel. Shilen sells a #3 .375 barrel; BTW...

Can you tell I want one???

You may prefer the .458 necked down as you will suffer fewer splits even when annealed.
Great variety of .375 bullets available but I found that the Barnes are all too long. Better to use, Hawk for the heavies.
I use the 220 gr. Hornady and 260 Noslers which are just perfect.
Mine is built on a vz-24 with a pac-nor barrel at 24 inches.
I find it to be a very nice caliber to load for but wish I had correct headstamped 'cuz I also have a 30-338, 416 T, .375 and 338 WM and .458 wm all on basically the same brass.

The .375 Taylor is an outstanding wildcat that almost duplicates the the .375 H&H's ballistics.

Click on "Reloading Data" at the .416 Taylor page, and you will see the .338-375 (.375 taylor listed).

For hunting less than dangerous game I'd still prefer the standard .338 or .358 Norma Magnum but if one wants to step up to the task of dangerous game the .375 Taylor will stand toe to toe with the old .375 H&H.

That said it's a wildcat and suffers that distinction. Personally I believe it's sellable as a factory load. Obviously the Winchester and Remington ammo makers don't see that view.

I was getting just shy of 2,600 fps with mine shooting 300 gr old style Nosler partitions. Wonderful rifle, wished I had never sold it. I formed brass by putting 12 grains of unique in a 338 case and then filled the case up with cream of wheat and stuffed a wad of tissue into the case mouth to make a plug. I chambered them and pointed the muzzle up and pulled the trigger. Cases had to be trimmed but I never split a neck.

I have done a fair amount of hand loading for my neighbors 375 taylor and it is a very flexible and effective round. R15 works best with all bullet weights, but any powder that works well in the 308 winnie will do well in the 375 Taylor as the two rounds have identical expansion ratios. This also means that a 22 inch bbl is all you need. If it were a factory round, we litterally would have no need for the 375 H&H or the 338 winnie...that puts it in a class by itself.

I'll second that to some degree. If winchester were to release the "375Winmag" I see great success for that round if it was to happen, but I suppose they dont want to rock their own boat in regard to their 338,375 sales. A .375T/W certainly makes much more practicle sense than a 325WSM.

Thanks for all your replies.. I'm thinking seriously about building one.. now to watch for a SS Ruger 338 to canabalize... Les

Don't just look for that 338, the 7mm mag and 300 Mag are the same case size so any full length magnum Ruger will do.

Friend of mine has one, loves it! Think of an H&H in a compact size. Also I agree to use .458 win. mag. brass. As 375-458 kinda sounds better as well! What ever you do get a tapered expander ball with your die set. My friend experimented and even used 7mm Weatherby brass successfully. You will not be dissapointed by this cartridge!

I have heard that felt recoil is different than the standard .375 H&H? (harsher faster recoil
impulse) Any experience?

I would agree with this.

I have a .375-.338 reamer. Let me know if you need someone to barrel it for you.

if 375 in a standard length action without alot of work, te 376 steyr is the answer

I ain't too worried about ol Bruno when I carry mine in the woods.

Kinda follows what Teddy R. said "walk softly and carry a big stick."

My .338 Winny is a nice stick, but my .375 T is my BIG STICK.

Well no matter what you do or how dilligently you load this cartridge it falls short by a full 9 gr water in gas tank capacity from the H&H and by the same token if you do the same for the H&H it can be loaded to " almost but not quite " 375 Weatherby velocities.

Will it ever take the place of a H&H, even if someone produces it in a Ruger or a Winchester ? I doubt it.

HORSESHIT! It is no problem to duplicate the .375 H&H velocities with the .375 Taylor. I've done it with mine with no pressure problems whatsoever.

A question was asked about the recoil. It is less, IMHO. My .375 Taylor is built on a tang safety Ruger 77, 22" Douglas barrel, and a Ramline stock. The recoil is definitely less in that 7.5 pound rifle than in my 9.5 pound Ruger #1 in .375 H&H. Probably because of the smaller powder charge and the give from the synthetic stock.

I agree that using .458 Win. brass is probably the easiest method of making brass for the Taylor. A simple pass through the sizing die and then trim just enough to square off the necks. You can just use the full power load to fireform. I have made brass for the rifle from 7mm Rem. Mag. and .338 Win. Mag, but now use strictly .458 Win. Mag. brass. It is the least amount of work.

My velocity with the 300 gr pills at just under 2600 is about 50 fps more than what I am getting out of my current 375H&H. I have to agree with Paul.

I benched my wife's uncle's .375/.338 one day with some stout 250 gr. loads. It's in a 9 lb. Mauser. I didn't notice it to be horribly more objectionable on the back end than my 8 lb. .300 Winnies with 180 gr. loads. Could be the fit. He's quite happy with its ability to put the smackdown on elk and bear.

Is the 375 Chatfield-Taylor a 338 Win Mag necked to 375, or is it a 416 Taylor necked down to 375 ?

But it can be chambered in the BLR for a light, easy carrying lever gun. I have to admit that I would have no use for one in a bolt action though.

Both. Or it is a 458 necked down to 375. It uses the same basic parent case as all the classic medium length belted magnums.

I'm wondering about the body length and shoulder dimensions. The 416 Taylor I had did not have a 338 Win mag body

.

My .375 Taylor is built on a Montana Rifle Co. M1999 with a Shilen 23", #4 tube. In the process of working up loads, I chronographed a LOT of them. I posted them back in August and September, 2004 in the Reloading forum (or maybe it was the Wildcat forum). 2800fps with a 270g Hornady, 270g Barnes TSX, or 260g Accubond are all easily obtained with AA2520. My best accuracy was slightly slower, around 2725-2750fps with the 270g Barnes TSX and RE-15. You can say all you want to about case capacity, but do a search in the reloading forum for .375 H and H and you will see that very few people are beating those velocities. Recoil is a BIG push, but not sharp. I've not shot a .375 H and H so I cannot comment on the recoil comparatively. I make my brass from virgin .338 WM brass, one pass thru the .375 Taylor die takes care of it. I have not had a problem with split necks, but have only reloaded brass 2 times so far. Why did I build a .375 Taylor? My brother left me 200 new .338 WM brass, I already had built a .338-06, and I needed a THUMPER. The .375 Taylor fit the bill perfectly. No regrets....well, maybe one. It has a very nice Borden Rimrock stock, but it is crying out for a Bastogne walnut replacement. The .375 Taylor would make one hell of a factory round.

The case capacity of the Taylor is 87.92 gr vs. the 96.37 gr of the H&H and as they share common parentage in terms of case base and head diameters the one is simply more of the other in terms of capacity.

So no matter what you do if we load to maximum capacity and to modern standards the rules of internal combustion dictate that we can get more powder into the H&H case and more powder means more FPS. As long as we remain within the limits of safe pressure the velocity relationship all things equal is linear. For each grain of powder we will get a contant velocity yield.

For the same reason an improved 375 H&H will beat out the standard H&H.

Apply the same standards to both and the bigger case capacity case means more FPS.

The same rules apply when we compare a 38 special to a 375 magum vs a 375 maxiumum or in rifles a 7mm rem mag vs the 7mm Weatherby vs the 7mm STW, In large bores the 458 Win vs the Lott vs the 3 inch express.

I think it all boils down to pressure. According to one manual I have, the .375 H&H is loaded to a standard 51K C.U.P. for pressure. Now if the .375 Taylor is also loaded to 52K C.U.P., why wouldn't the velocity be at or near the same as the H&H?
IIRC, Bob Chatfield-Taylor designed the round so as to be able to use the shorter action. Whether it was really necessary or not is really a moot point. It's what he wanted and frankly, it is a damn good cartridge.
I have rifles in both cartridges and the Taylor defintely kicks less, probably due to the smaller powder charge. My rifle is a 7.5 pound gun on a Ruger 77 tang safety action. Stock is a Ramline that replaced the broken Ruger stock. My .375 H&H is a Ruger #1 that weighs about 9.5 pounds with scope. Felt recoil is definitely more with that rifle. Whether that is based on the difference in stock design, powder charges, the synthetic stock of the phases of the moon, I haven't a clue, but the difference is there. The round is also very accurate in my rifle. maybe it's the same reasons the WSMs are considered to be so efficient. maybe so.
Paul B.

I thought that Taylor did not design the 375, that it is really a 375x338, but that since he did do the 416 Taylor everybody just calls this the 375 Taylor. am I wrong?

I have a 300 Win mag with a bad barrel and am interested in building the 375 Taylor. I have read everyone's comments and they have been great. However, I am curious as to what animals have been taken with this cartridge, and especially at what range. It appears that there has been a lot of range work with chronographing, but the proof is in the pudding, or how well and how quickly it brings down big game, especially dangerous game.

Thanks in advance to everyone.

375 Taylor = (for all practical purposes) 375 H&H. That about sums it up.

I'm seriously considering ordering a run of brass from Quality cartridge.

Price is about $1.75 each depending on quantity.

anyone want some? There is a 200 piece minimum

Please PM me

Vapodog,

What would the headstamp be on the brass from Quality?

I've asked them for cases stamped 375 Taylor

I've heard others say it's stamped
.375/338 and that's not what I want for a custom stamp. I haven't marked my barrel yet so can mark it anything I need to match the cases.

I would like to know how you are breaking the laws of physics, the same with less. Impossible. Loaded to the same pressures, the H&H will be faster. You are comparing higher pressures in the Taylor with lower pressures in the H&H.

SDH/ALF--I can just picture both of you banging your heads against the desk

SDhunter,

You are absolutely correct - it is always SHOT PLACEMENT, SHOT PLACEMENT, SHOT PLACEMENT.

I have a 375 H&H that shoots just fine. I also happen to have a Husqvarna 300 Win Mag with a pitted barrel. Since I have a passion for the Husqvarna actions, I thought it would be interesting to put together a 375 caliber, but the action is not long enough for the H&H.

So far, I haven't seen any posts on the "proof in the pudding" - that is, has anyone killed any critters with the 375 Taylor?

Your comments are well taken.

Anyone who has worked with the .375 Taylor says for all practical purposes, the ballistics will be identical. I have considered one for a long time as I have a good C-Ring FN action in .338. I'd rather go with the wildcat than pay someone to go to the headache of lengthening it for a .375 H&H. That in my opinion is the reason for the .375 Taylor, plenty of brass available, makes it a reasonable wildcat.

Actually, I'm not breaking any laws at all. Standard pressure level for the .375 H&H according to my latest Winchester loading booklet is 51,500 CUP. For the .338 Win. mag., it's 57,000 CUP. Obviously, my pressures are probably closer to standard .338 mag. pressures if truth be known, but if 52K CUP will squirt a 300 gr. bullet at X velocity, doesn't it stand to reason that that SAME pressure should push that same bullet to at or near the same velocity from the shorter case? For one thing, I am not trying to gain most velocity from the Taylor, only duplicating the velocity that the older case puts out. I could easily load my .375 H&H Ruger #1 to higher velocity, but why? All I want from my rifle is a duplicate of what current factory ammo delivers, and I do that with no pressure problems whatsoever. Probably my pressures in the Taylot might be closer to about 55K CUP, but who knows.
All I can say is the round is very accurate, it delivers what I want it to give, the rifle is light enough that it's a jow to carry and it doesn't kick the bloody snot out of me from the bench. What more could one ask from a very potent rifle suitable for some very large and potentially dangerous critters? I sure don't see any complaints coming from those who have built up one of these rifles.
As far as how well it works on game, if I ever get lucky enough to draw a tag for elk and get a shot at one, I'll damn well let everyone know how well it works. Probably, just fine, thank you very much.
Paul B.

Wonder if anybody has talked to Kimber about building a 375 Taylor now that they are doing standard length receivers in 338's? Way cool! a 375T Montana!!! Could be a real winner!
Any other semi custom suggestions for a "ready built" rifle? Or how about CZ?, since they are now offering for 2006 their Medium Magnum 300WMg Lux thru CZ-USA at 7.72 lbs with 3 rounds down.
