As I'M new to the 375 I'd like to hear about people's pet loads.
Cases, primers, powder, bullets c.o.l., speeds - the words, if you don't mind sharing. I've got most of the books - but nothing trumps actual experience - and right now, when it comes to the 375 - that is something I'm lacking.

Brian, I shoot Noslers top end book load of 73 of R15 with the 260 Accu a bit, it shoots well and runs @ 2700 in my 23" barrel.
I almost forgot to say that this is my fire form load for my 375 Roy.


Dober

I shoot mostly 300 grainers; Parts, I Lock's and Hornady solids. 78grs. H4350 works for me. Another 2 grains of the same for 270 Hornadys. Each use WW cases and Fed. 215's. Speeds are 2,500 and change for 300's and 270's are slightly under 2,700 from a 24 in bbl..

H414/W760 is supposed to be a great powder too; never used it in 375 HH.

Hope you njoy the 375!

I have used Win brass primarily but will have to be switching to Rem brass now that Win has bailed (have some but haven't used it yet)

Primers: CCI 250 or Fed 215GM

Powder: RL15 for all. by far the best, IMO

I've used Nosler, Hornady, X, and TSX in 260,270,300.

I've gravitated now to using primarily 300 TSX (low 70 grs of RL15) but have had good results with 270 TSX (mid 70 grs of RL15).

I like the 270gr TSX over a charge of RL-15 and Fed 215M primer.

I've gotten good results with IMR 4064 in the .375H&H as well.

76 grains of 4350 under a Woodleigh 270 grain bullet. Kills everything that you could possibly want to kill. Primer or make of case makes no difference for this load.

78.7 gr of IMR 4350 under 300 gr Nosler... .5" from my rifle at 2600 fps...

I like IMR-4064, RL-15 in my .375..I like the 350 gr. Woodleighs in RN and PP, the 300 gr. Northforks, GS Customs flat nose solids are my favorite, Northforks has been saved and it is one heck of a bullet and I just love those Cup Points for Buffalo. The 250 and 300 gr. Sierras are good deer and elk bullets and cheap..

Truth is there is little about bullet failure where the .375 H&H is concerned, 300 grs. of bullet failure is rare indeed.

Sorry about my previous post, it was supposed to go another thread.

At the moment, I'm shooting 72 grains of RL15 under a 260 grain accubond in a 700 XCR. My previous .375 was a stainless Ruger #1 which shot the same load but used the ballistic tip. The Ruger was about 1.5 pounds heavier but kicked worse ... stock design, I guess. The Ruger was more accurate, around .75 inch, the 700 is more in the 2" range, both for 3 shot groups.

Prior to that, 20 years ago, I had a blued #1 which I fed a 270 grain hornady spire point and 70 grains of 4064.

That reminds me, though lower velocity, the 700 threatened accuracy with the accubond and 4064 the other night, .8" at both 68 and 69 grains, so while it's not tested, one of these days I'll re-shoot at 68, 68.5, and 69 and see if the results repeat.

Tom

I have a load for my 375 Wby with 235 TSX's that shoots quick and shoots well.

I kind of wish that they'd make a 250 TSX...

Dober

It does seem that a 250 gr TTSX with a boattail - and a plastic tip - might be the "perfect" 375 bullet for North American use doesn't it?

Bring on the tipped homogeneous bullets.

I used a 270 FXB over 74gr od RL 15 for 2730fps. Could have gone for more velocity but a 270 at that speed gets things done. By after the new year if the 9.3x66 doesn't show I will most likely go with the 375HH in an 85, but i really want the 9.3

Brian, what kind of 375 do you have, does it have a 24" barrel?

Wholesale Sports in Kamloops had the gun, the scope, the rings, the powder I wanted, the dies, the ammo, the bullets, the cleaning equipment - on the rack.

And a knowledgeable staff - to boot.

The 19 year old kid (who initially I didn't want to deal with - as I preferred some one with more knowledge) knew the answer to almost every question I asked! What a kid! He's built his own rifles and competition 1000 yard competitions! He reminded myself of a young "Me"!!!

Do yourself a favour - order one though them - and visit me when you go to pick it up!

It's got a 24 3/8's barrel. Sako Synthetic Model 85.

It's the best rifle I've ever owned in my life! Totally slick, foolproof, absolutely accurate and it has a perceived lack of recoil - like you wouldn't believe! Light too - at 7 lbs (or a little under!)

I'm almost embarrassed by how much I love it.

Did you read my report on it in the "Hunting Rifle" section?

My wife's is a bit jealous!

I mean - doesn't every man play with his new rifle in bed every night? I must have cycled five hundred rounds though it - and cycled the bolt a few thousand times by now. I can drop the clip with one hand over and over again - in a practiced second.

Just for grins I'm gonna try loading the 235 gr. Speer on top of RL15 this weekend. Hoping to get some nice tight groups out of that. Next I'll try RL15 under those Hornady 220's / 225's, but I'm betting they won't like RL15....

Brian, if they came out with a 250 TTSX I'd be big time all over it!

Dober

One load that I like for big game here in the US is:
Speer 270 gr BTSP
70 gr of IMR 4064
Winchester Case
Federal 215 primer

Works like a death ray on deer & antelope.

WyoJoe-I've always been sort of intrigued by that bullet, you ever used it on elk and have you ever found any in critters?

Thx

Dober

Seriously, Dober. Do you think any critter would know the difference?

gotta love those Sako actions, I have a Finnlight in 3006, its an MOA shooter out of the box and one of the best triggers I have had the pleasure to squeeze. i will give the 9.3 'till after the new year and then look for what you have, although i like shorter barrels. I shoot my cousins 75 in 338 win sometimes and as far as recoil goes it is not worth discussing. I pcked up a 75 in 300wm last year and promptly turned around and sold it. methinks I wish I had it now and would rebarrel to a meaningful caliber.

Good write up brian and photos as well. I think if you run a tsx or fxb 270gr bullet you will be happy. The 37hh i sold a few years back was an old, but like new, C grade custom out of the Rem custom shop, it was a 3 shot MOA first load I picked, 74gr RL 15 and a 270 fxb for 2730fps. I shot 3 moose with it, one a calf, one a 4 point and the last a mature bull, mid 40"s on the rack. The last one gives credence to the 375 that no smaller caliber can match, I'm up late as I have had bad cold and need a neo citron, anyway, 5 yrs ago i was coming out of a cut at near dark, I glaced across an old grown up landing as I waent by and saw a moose face, so i stop expecting to see another cow, was seeing lots of cows, I looked at it and saw no horn in the twilight, so i looked through the 375's scope and all i could see was a mooses face until it turned and then saw the 1/2 rack, I pulled the rifle down and back and squeezed of a round, still could only see its face as it was behind a run of willows 80yds away. It went down hard and stayed there. It looked like a softball went through the heart. There is no lesser caliber that i would have taken that shot with, except maybe my whelen, but certainly no 30 caliber no matter how fast it was running. Big animals in tough conditions warrent big well constructed bullets, the 375HH does that and the shape of the cartridge lends itself to slick feeding in the rifles action, although sako's don;t need any help in that dept.

If you want to duplicate factory 300 gr loads , go with 76 to 78 gr of H-414 or WW 760 .

As far as the perfect N americano bullet I think we got it with the 260 accubomb.....despite the "bomb" moniker , they drill thru elk like swiss cheese .

My favorite for years(for NA)is the 250 Bitterroot and enough 4064 or RL15 to give app 2900 fps;I use the 250 Sierra for practice.A 250 Swift Aframe would be my choice today if I did not have the Bitterroots.

Used 74 gr RL 15 and WW LR primers (couldn't find Federal) with 270 gr TSXs on a plains game hunt this spring. Very accurate, very effective load.

Ah yes of course I do.......it was only a wish not meant like if they built it it would all of a suddent kill way better than the rest of them.

Dober

In all seriousness, a boattail and a nylon tip could combine to add 100 yards of effective range to a 375 H&H - using Barnes bullets recommendations for suggested impact velocities. Barnes recommends over 1900 fps.

By comparison, the 260 grain Nosler Accubond - maintains that velocity for more than an extra 100 yards.

I just wish Barnes would add a boattail option and a tip to their 375 offerings.

Me too Brian, plus I feel that the tipped bullet would help to facilitate expansion especially at long range.

Dober

This is a great thread; gives me some ideas for loads for my own new 375...

I haven't used it on elk but from the performance on deer & antelope I wouldn't hesitate to use it.

I have only killed one elk with a .375 & that was with a 270 gr Hornady Interlock. Never again! It was a calf & I hit it @ about 50 yards. The bullet disintegrated & never exited it's chest.

I know a guy who used one out of a .375 Ultramag on a buffalo here in WY. It completely penetrated the buffalo from side to side.

The 260 AccuBond is a VERY stout bullet, capable of pretty much end-to-ending elk or similar game. As with Partitions, they make the bigger AccuBonds tougher; I know of at lest two Cape buffalo that have been taken neatly with it, one with a frontal shot. It really flattens out the old round too.

I generally use around 70 grains of Reloder 15 with 260-270 grain bullets exactly how much depending on the rifle. This will get 2700-2800, again depending on the exact charge and the rifle.

Also about 75 grains of H4350 is good for the 300-grain. Muzzle velocity will be 2500-2600, again depending.

Another good load is the 220 Hornady flat-nose with 35-37 grains of IMR4227. This gets around 1900-2000 fps and can usually be adjusted to shoot to the same place as a heavy-bullet full-house load. This is not only pleasant to practice with but does fine on woods deer--and even prairie dogs. Essentially it's a modern .38-55 load.

All you need to know: BEST 375 H&H LOAD....EVER

jorge

Okay

I like RL15, my standard load for a few years has been a 270 North Fork with 72 grains of RL15, which goes 2770 fps in my Whitworth with a 24 in. barrel. I have pretty much always stuck with RL15 or 4064 in my .375's, but others have used 4350 and H414 with 300's. One of these days I'mgoing to try some Big Game since it works so well with almost all other medium bores.

JB
In your opinion, would the .375 260 grain Accubond be a good choice for brown bear?

Thank you

JB,
I would like to hear your take on the Accubond also. I met a guy during elk season that had used one in his 375 Ultramag for a bison and I was thinking of trying them in my .375.

Brian, my .375 load - at least for now - is the 270-gr TSX over 77.5 grs. of H4350, Win cases and Fed 215 primers. It isn't hot in my rifle at 2670 fps. but shoots just fine. Here is a representative group and a bullet from a Burchell's zebra, the only one in seven on a Namibian trip that wasn't stopped.

I came to love the cartridge in my first and brief visit to Africa and came to understand why it is a classic based on it's history there.

Sorry, I can't get photobucket to deliver tonight but it shoots under 1" and my best group with it is .38" if that means anything and Barnes couldn't have wished for a nicer mushroom than this one TSX I've been able to recover.

Gdv

I'm betting I'll eventually settle on the load I just shot (260 grain Nolser Accubond over 73 gr of Reloader 15 ) or - more likely, the most accurate load I'll get with a 270 gr Barnes TSX - generally speaking - my all-time favourite bullet made.

The only thing likely to change that - would be if Barnes decides to boat-tail and tip the 375's - with a TTSX!

For accuracy, I like IMR-4064, that is the powder I use when I want to know if a certain .375 will shoot..It seems to work everytime...My hunting loads are sometimes RL-15..Those are my chosen powders..

For the big stuff I wouldn't consider less than a 300 or 350 gr. bullet in the .375..If I want a lighter bullet I'll use a lighter caliber..In fact I am pretty much sold on the 300 gr. bullet for lighter stuff like Impala, Elk or deer..It kills well and you get less meat loss.

Ray,
I used one of your reccomendations. I put a 270 Speer BTSP over 70 gr of IMR 4064 (used Fed 215 primer) and it flat puts the smackdown on deer & antelope. Didn't get the chance to try it on elk though. I kind of like that Speer bullet for big game in the US.

I've never hunted a Brown Bear but hope to some day. Based on what I've read here and told to me personally by some very experienced and learned friends, a 260gr Accubomb would be just about at the bottom of my list for Brown Bear;right next to the Sierras. TTSX baby, driven FAST! jorge

From what I've seen I'd have no misgivings about using the 270-gr TSX @ 2700 fps on everything (incl brown bear) up to cape buffalo; for them I'd go the 300-gr route in a TSX or other premium but I'd also rather have a bigger hole in the end of my barrel for buff.

I am not a big Sierra fan, but some of the the local gun nuts here all use the 250 gr. Sierra in their .375s for elk, and they always show me those pretty little mushroomed bullets, I have seen so many of them now that I am convienced they are an excellent elk bullet at around 2800 or so FPS. Never used them but I am tempted. They sure are accurate in my gun..but I would not choose them in the thick nasty dark timber swamps where the big bulls hide..I will stick with my 300 gr. Woodleigh in my .338 for that or my 350 gr. Woodleighs in my 375, cause I have to shoot them up the keyster, never get any other shot it seems.

I've not tried the Sierra 250-grs either. I guess I'd be more inclined to go to the 260-gr. Nos Part for a light bullet load in the .375, but if the Sierras work....

Being as you're a heavy bullet fan another candidate you might try in your .338 for elk in the thick stuff is the 275-gr Swift A-frame. I bought two boxes for my 340 Wby when I had a brown bear hunt on tap. It fell through but they are quite accurate at ~ 2675 fps in the WBy and I have no doubt they'd work well

Gdv.

I have been working with the .375 H&H throughout the summer and have really grown fond of this classic caliber. It reminds me of an artillery shell! Anyway, the load I finally settled on for my Rem 700 XCR features the Barnes 270 grain TSX, in Rem neck sized brass, Fed GM215MAG primers, and over 72 grains of Vihtavuori N-540. Average muzzle velocity is only 2,614 fps out of my rifle, and finding this powder has become a real pain in the backside for me, but it really performs in my rifle. Here�s a five shot and three shot group at 100 yards, as the rifle�s thin barrel heats up it strings vertically downward:





Hope to have the opportunity to bloody this load and rifle on an upcoming elk hunt in Northwestern Colorado later this month!

has anybody used the 250 trophy bonded....loaded by federal in their premium line. I shot some this afternoon I found that were leftovers from when I was trying loads for Africa. Never got around to shooting them then, but I pulled them out thinking I might use them on a boar hunt. The rifle liked them just fine.


I would think they ought to go through the biggest hog in Tennessee from either direction but would like to hear from somebody who has shot something with them.

Badge-

H4350 is your answer.

The two powders I use in the 375 and in my 375 Wby are H4350 and R15. I'd try both of them and see which one perks the best.

Dober

70 gns of varget with 235 speer and 260 partition goes great in my 1938 model 70. 2660 fps the partitions i havent chronyed the speer. 78 of h4350 is just as good

Haven't tried them yet, but Alaska Bullets shows two flavors of 250-grainers. My .375 WeM likes Sierra's with 4064 but not very fast...

Has anybody loaded those 265 grain GS monos yet? I seem to remember somebody loading them to over 3000 fps with RL15 or Varget - that range of powder and the pressure was supposed to be low. They appear to have great BCs and are long for weight which they retain most all of. They seem like a perfect hunting bullet. Easy on the gun, flat shooting, deadly.

Not a .375 but one of my hunting buddies neatly took a large Russian brown bear with a .325 WSM and 200 gr. Accubonds, no problems.

A number of powders work well in the .375 H&H. That said, IMR 4064 WAS the factory loaded powder for many years in the .375 H&H for good reason, it works very well.

any others ideeas and reloads for 375hh would be apreciated,for my soon to be done montana 1999 ss rifle..tnx

A load I just tried today while using VV N-140. With 66.5grs behind a Swift A-Frame 300gr bullet lit by a Fed 215GMM, it placed 3 bullets in a vertical row, all touching. This powder leaves enough room in the case to be used with any 300gr bullet and not have a compressed load. 67.5grs of IMR4064 does almost the same thing.

Remington 700 Safari

71 grains of RL 15

Barnes TSX 270 grain

64 grains RL 15

300 grain Fail-Safe

I've most shot the rifle standing up after I got it sighted in and the few loads I've tried checked.

I don't mind the thump standing up. Off the bench, thank the good lord for the Caldwell Lead Sled.

Goodnews,
In my .338 my all time favorite load in the thick stuff or in Africa is the 300 gr. Woodleigh, it really smacks'em down..

In the 375 I like that 350 gr. RN Woodleigh for elk and softer skin animals, again it smacks'em down. It also works well on buffalo in herd hunting as it stops on the off side skin expanded to the size of a quarter or bigger.... The 350 gr. PP Woodleigh is tops for buffalo with ample penetration for angle shots. I use the PP on bachlor bulls and the RN in herds..

So Ray, not trying to be a smart ass or anything, you think a 600g .510 caliber Woodleigh PP should hold together fine for buffalo then? I'm trying to decide between it and the 570g Barnes TSX. Apologize for the mild thread hijack

Regards,

Chuck

Colorado,

I can tell you without any doubt what so ever, it won't make one iota of difference which weight you use considering the way that big bore hammers buffalo. The Woodleighs work just fine and you couldn't pick a better bullet. It won't come apart but if it did it would scatter enough lead and copper around inside the bull to make him really sick...about like a handgranade..

Thanks Ray, back on topic, I liked the way the 250g A-Frames shot through my 375 H&H as I recall I used IMR 4320 for a deer, elk and black bear load. I got 2850 fps, no pressure signs, good accuracy and light recoil.

Chuck
