Posted By: CZ550 350gr TSX in .375 H&H - 02/24/23
Has anyone tried the 350gr TSX in their 1 - 12 rate of twist in their .375 H&H?
Posted By: bowmanh Re: 350gr TSX in .375 H&H - 02/24/23
I haven't, but I'm wondering: in a .375 H&H what is the advantage of a 350 grain TSX? With a TSX, more velocity is helpful in promoting expansion and penetration, and you're not going to get it in a .375 H&H with its somewhat limited powder capacity.

If one were hunting elephant, a 350 grain solid might be a good choice.

For lesser animals, a lighter weight TSX would seem to be better. My son and I used 270 grain TTSX last year for buffalo and eland and they worked great.

Just my thoughts, but I'm curious about why you want to use a 350 grain TSX. I can't answer the question about the twist.

I Prefer the 270 grain TSX or TTSX in my 375 H&H

My dad used 270TSX out of a 20” barreled 375 ruger last year…. They worked perfectly.

I could see their usefulness out of a 375RUM or 378wby…. But not sure they’d gain anything out of the h&h….
I think it was Craig Boddington who wrote about how he felt they actually robbed the 375H&H of some of its versatility due to being considerably slower than “standard” weight bullets.

I was simply curious to see if anyone had used them. I recently picked up some 270 TSX and 300 TSX, and they also had some 350s - which I didn't know Barnes had made. Moreover, I wondered about their stability in a 1-12 twist. Some experienced African hunters have used the 350gr Woodleighs in their .375s.

Just a question for informational purposes.

I've used the 350 gr. Weldcore from a standard twist barrel. No issues with that one.

The heavier mono metal bullets usually are too long to stabilize in many rifles, plus one of the benefits of mono metal bullets is that they tend to hold together, so they penetrate well, and you can choose lighter bullets for the same penetration, yet get a bit additional velocity and shock.

If your curious I get it. Otherwise the 270 grain is fantastic in my 375 Ruger. Could not think of a situation where anything heavier would be better.

And so do all the African PHs I know who have experience with TSXs....

At least two factors favor the 270 TSX over the 350 or, for that matter, the 300.

1. With monos, higher impact velocity promotes full expansion until the expansion cavity reaches its limit.

2. The expansion cavity of all three bullets is identical.

I have taken buffalo at ranges from 35 to 150 yards. The muzzles velocities have been 2750. As the ranges increase there is an obvious decrease in expansion. Sample size 11 buffaloes.

Have observed the same expansion/impact velocity relationship with 130 & 140 Barnes monos in my 270W.

This also may explain why the 300’s are more likely to fully penetrate buffalo; they don’t expand as widely which results in deeper penetration.
Posted By: Mule Deer Re: 350gr TSX in .375 H&H - 02/25/23
Yep, which is why in general TSXs kill quicker when they're lighter and faster.
Posted By: RinB Re: 350gr TSX in .375 H&H - 02/25/23
I am going to see if the 375/270 LRX bullets expand more readily. I suspect they will because of the plastic tip and the slightly higher impact velocities due to the higher BC’s.

Not a gun writer

The 350 gr TSX shot just fine out of the .375 H&H Weatherby vanguard DGR I owned. I've sold the rifle so I no longer have my notes or test targets so I'm going by memory. 3 shot groups at 100 yards were in the .8 to 1.2 inch range; groups were better with the 300 and 270 grain bullets. As one would expect; significantly slower velocities.

When I was chatting with outfitters before confirming a trip for buffalo in 2021 I asked about preferences for bullets, most said use any good controlled expansion bullet in either 270 or 300 grain. One said do not use the 350 grain TSX as they had one pass through a bull and kill? injure? a buffalo that was not seen on the far side. Their comment was they preferred the 270 g TSX as it most often ended up under the hide on the far side in broad side shots and did a great job killing buffalo.

I was unable to get any 270 g Barnes except for the LRX, no surprise it worked just fine on 4 bulls. There is a post about the hunt in Africa forum.

Add this into the comments above and I would conclude if you want to play with the 350 g TSX fill your boots, if you want to hunt use the 270 g.

GRF,

The pass-through point is a major one when hunting buffalo in herds. A good friend, another gun writer who really likes lever-actions, chose a .45-70 with high-quality "solid" bullets for his first buffalo hunt in Zimbabwe. It was in thick cover, and he killed a good bull--and also an unseen cow behind the bull. Luckily the bullet landed in the right place on the cow too.

The first bullet I put into a Cape buffalo was a 300-grain Fail Safe from a .375 H&H--which in my experience worked a LOT like Barnes Xs. Luckily it was in pretty open country in Botswana, and there were two big bulls at the end of a walking herd of 250 or so. Russ whispered for me to make sure the bulls weren't in line with each other before I shot.

I aimed at the shoulder when the bull paused, but he started walking again just as I pulled the trigger. The bullet landed just behind the shoulders but went through both lungs--leaving an exit hole the size of my fist. Have hunted buffalo more than once since, and my experience (both my buffalo and those my companions have taken) is that an expanding bullet that DOESN'T exit is preferable, as most PHs have suggested.

They also might kill quicker, because in general a wider "mushroom" makes a bigger hole.

Thanks for the reply John.

I recall reading the .45-70 story in Successful Hunter or some other Wolfe publication.
Posted By: CZ550 Re: 350gr TSX in .375 H&H - 02/25/23
So that settles it on the 350 TSX. I never knew they existed until I went to a large emporium where I do most of my shopping - was curious about them.

I do a lot of correspondence with a fellow who lived in Alaska for many years and had shot all big game there several times over. And he owns a pile of big bores. His favorites are .375s, including the H&H. He recommended (as I was scrounging for bullets and found a source for the TSXs) the 270, before I went shopping. So, thanks to all, and the 270 TSX is the consensus.

This is not my first .375 H&H. I've owned three others in the past.

Thanks again.

Just my opinion…..the 350 TSX due to it’s length, would use up too much powder space and would be severely detrimental to velocity. For bigger game (elephant, buff, ect.) I think that you’d be better served with the 300 TTSX.

For all around use…..the 270 TSX or LRX would be good. For smaller big game (up to moose) the 250 TTSX would do pretty good from an H&H…..but, I’d still prefer the 270’s. JMO memtb

Bought a box of reloaded 375 h&h at a gunshow for $20, 49 rds 33 loaded with 300 gr ww silvertips. Will pull the bullets to see how they are loaded but has any one used 300 gr ww silvertips?.. mb
Posted By: Mule Deer Re: 350gr TSX in .375 H&H - 03/01/23
Are they old ones, not the present "Ballistic Silvertips"?
Posted By: Magnum_Bob Re: 350gr TSX in .375 H&H - 03/01/23
JB they are the old ones. I didn't really need anymore 375 stuff but I'd dang near go to hell to try the stuff of yesteryear. I find going retro pretty interesting so I do when I can...mb
Posted By: Tom2506 Re: 350gr TSX in .375 H&H - 03/01/23
I remember reading an article from Sheriff Jim Wilson, where he and one of the instructors from Gunsite, used that bullet with success. Can’t remember her name though.

Thanks, Tom

That is Il Ling New. She hunted Buffalo with them and felt they hit harder out of the 375 than the 300 or 270 grain bullets (as I remember her saying it)
Posted By: GF1 Re: 350gr TSX in .375 H&H - 03/04/23
Is there any data on the 250 TTSX bullets shot into buffalo. I am aware the of the general affection for the 270s for this purpose, but is there any data from actual hunting with the 250s?

The original Silvertips were all over the place as far as expansion/penetration. Once had a 150-grain from a .30-06 factory load come apart on the shoulder joint of a forkhorn mule deer buck, the range about 200 yards. The core disintegrated, and the jacket came to rest on the ribs behind the joint. Luckily, I was able to track the buck down after half a mile, and put another in the ribs behind the shoulder, which penetrated and killed it. On the other hand a friend killed a pile of elk with a particular lot of 130-grainers from his .270 Winchester. The ones he recovered from under the hide on that far side (and he had quite a few) were all perfectly "mushroomed."

A good friend, the late Walter White, killed one of the biggest brown bears listed in B&C on Kodiak Island, using his pre-'64 Model 70 .375 H&H and 300-grain Silvertips. The bear was on the other side of the Zachar River, and it was a wet day--as so many are on Kodiak. The bullets mostly came apart on the bear's wet hair and hide and mostly failed to penetrate the chest. Walter didn't know exactly how many times he shot, but did remember reloading the magazine twice before one got inside the chest and killed the bear.

I never knew this bullet existed. Might have to try it out on an 8" twist 375 Raptor. This might be my subsonic load!
Posted By: Magnum_Bob Re: 350gr TSX in .375 H&H - 03/04/23
JB that is exactly what I wanted to know thank you. I am sure that I'll never get up there to try them out on bear but might shoot a deer or 2 with them..mb
Posted By: Mule Deer Re: 350gr TSX in .375 H&H - 03/05/23
You're welcome!

Have mentioned this before, but the best "media" I've found for testing bullets that might be used on game larger than deer is a stack of dry newspaper. Over the last 30 years that's revealed flaws in a number of bullets--and also shown where the "same" bullets were improved by the company.
Posted By: Puddle Re: 350gr TSX in .375 H&H - 07/09/23
Just had a box of the 350 gr. TSX drop in my lap. Gonna load them in a standard twist H&H to ~2,300 fps using Big Game and see what gives.

Never used them before while hunting, and I don't really expect to as well. In the H&H I've relied on the 300 grain A-Frames and the 350 grain Weldcore.

I wonder what the minimum recommended impact velocity is with these? I'll have to ping Barnes about that in a couple days.
