Home Forums Hunting & Shooting Express Rifles and Big Bores Only The .375 -cal 250gr TTSX, anyone using them or with experience? Results ?

Bighorn, thanks for your input.

"and an African lion" - about 450 lbs, maybe?

I'm hunting black bear and those 250gr TTSX's are for that purpose. Some bl. bear can pass 600 lbs, but, of course, not the same critter. Nonetheless, they are powerful and fast. And that's not all fat. When they want to chase prey (elk or moose), or get excited they can make 30 - 35 mph. Seems like those 250 TTSX BTs are about right for the task.

Spring 2023

Loaded 250 TTSX to 2800 with Varget not maximum

Shot 5 Cape buffalo. First three were down with a single well placed shot. Last two were done after the first shot but each got a second to insure they stopped in a place they could be more easily recovered.

I don’t see the need for anything bigger provided one can shoot well. If one can’t shoot well with a 375 then something bigger isn’t going to improve the outcome.

I’ve used that bullet on a few bull moose and a bear with good results.

Thanks all... it looks like I've made a good choice as an all-around bullet for anything - now to get the accuracy I want at a decent MV. Bear hunt starting again on Sept 1st.

I’ve used it (though at a bit more velocity) on several things from coyotes to moose…..I think you’ll be pleased.

Though, for me, they’ve made there last hunt. I’m working on a load with the 270 grain LRX’s. Slowly working up charges while shoot only during the heat of the day. The last 3 shot group was 1/2”, the previous groups were just a bit under 3/4”, but the velocity was a little lower than I was looking for. I’d love to get another 30 to 40 mv without pressure problems……and maintain that 1/2” group!

We will be waiting for the story! 😉 memtb

I used the 250 TTSX in my 375 H&H Mag to take a couple of crop damage deer this past summer. Both were 150 yards and were DRT.
I shot a buck this year with the Nosler 260 E-Tip at 60 yards and it was DRT. I did recover the bullet in the hide in front of the off shoulder, it was a perfect mushroom.

A useful characteristic of the Barnes 0.375” 250 gr TTSX is that it will expand easily in lighter game while holding together for deep straight line penetration in heavy, thick-skinned game.

Dependably predictable results when driven to the kinds of MV easily achievable in both the Ruger and H&H cartridges without abnormal chamber pressures.

This bullet has become my go-to projectile when a solid is not needed.

Some good information here.

The 375 W-by will chamber in my 375 H&H AI. Thanks for the info. I have only had excellent results with the TTSX bullets. I have some Barnes 235 grain X bullets 375 diameter someone could have along with some 225 grain X bullets in 35 caliber in the classifieds - $20 shipped if someone wanted them for testing.

It’s been a curiosity to me why the 250 TTSX seemed a stepchild up against the more famous 270 TSX. It’s got better ballistic numbers, can be shot faster and flatter. And should kill critters about as dead.

I’m glad to see it getting some respect.

Likely because most 375 hunters have zero need for "ballistic numbers, can be shot faster and flatter". I'll be returning to Alaska for brown bear next year and will use the same 270 gr TSX load I took six years ago. I am lost on why BC matters with the larger bore rounds?

Well, you’re right. Depends on the application.

I just like the 250 TTSX and like to see it getting some respect.

DF

My 375 loves the 250 gr GMX, 2800 fps seems like a do it all load

Would be interesting to see a side by side, GMX, TTSX.

DF

Likely that .375 bullets' modest BC's are the only knock on using a 375. Judged on its failures, like many things.

EdM to better respond to your comment……I am lost on why BC matters with the larger bore rounds

Not everyone uses the .375 H&H or one of it’s variations strictly for big game at close range. The .375 has been my “only” hunting caliber since 1982 or ‘83, and my AI since 1990. It’s been pretty effective on everything from coyotes to moose. I feel that it’s easily a big game cartridge to 900 yards or more with a good marksman…..though, my personal range limit is 600 yards in optimal conditions! memtb

With a G-1 BC of .449 for the Barnes 270 LRX ……it ain’t great, but ain’t that bad either! memtb

BC matters even at 100 yards in terms of impact velocity. Thereafter, the difference only increases.
I prefer the 270 LRX over the TSX for that reason.

The 250 ttsx is close, at .424. Remarkably close for being 20 grains lighter and noticeably shorter.

Very true, but I want the most potential penetration that I can get. While it’s only 20 grains of bullet weight….it offers a bit more potential penetration as well as a slight BC advantage……win-win!

I sent numerous emails and made many phone calls to Barnes asking for a TTSX or LRX type bullet at around 290 grains for the .375 calibers. Perhaps a bit too long and too heavy for the H&H…..but should really shine in the improved H&H’s, the RUM’s, and the .378 Weatherby. memtb
