Home Forums Hunting & Shooting Africa The 270 gr TSX 375 H&H

Haven't used them but I would bet there wouldn't be much difference in penetration between the two, just wanted to see if that assumption is correct.

I've used the 300 grain TSX for Buffalo and plains game but I'm just working on switching to the 250 grain TTSX for my next trip.

They have better B.C.'s than the 270 TSX, shoot a bit flatter.

They may open better than a TSX, not too sure about big critters like buff. Maybe they wouldn't shoot thru a buff like the heavier TSX's reportedly do.

My good bud killed a nice buff in Zim with a 400 gr. TSX out of his Ruger .416 RSM and it didn't go thru.

The 400 grain TSX is too long for the standard twist in 416 and tend to not penetrate as well as they could if shot form a 12 twist. The 350 TSX doesn’t suffer this problem.

Interesting about twist.

From what I've read, the std. Rigby twist was 16.5. The Rem 416 and Ruger RSM are reportedly 14 twist. My bud shot very good groups with the 400 TSX off the bench and practiced a lot shooting it offhand before leaving for Zim. And, he's an excellent marksman, has been since he was but a lad.

An aside on his shooting prowess. He always loved to shoot even when pretty young. A neighborhood dog showed up crippled, had been shot. The owner blamed this lad, knowing he liked to shoot. Lady across the street said it couldn't have been him. Asked how she could say that. Her reply, if this boy had shot your dog it would be dead...

Not a bad legacy for a young lad...

Found that out about 10 years ago, to my dismay. 400 grain TSX wouldn't shoot through a wildebeast and turned 90 degrees in a buffalo. Now everyone seems to know that, but the first guys were heretics.

Is there any parallel with 300 vs 270 monos in the .375 H&H?

DF

My guess is the 270 might out penetrate the 300, but if it didn’t I doubt there would be much difference at all.

My two recovered bullets from my trip to Zimbabwe last year. The 350 gr TSX via 416 Remington.

The top one was the first into my buffalo (~110 yards) slightly quartering away. In at the crease of the shoulder and found in the lower off shoulder. A second one through the lungs passed through.





The lower one went in a very quartering away waterbuck and was found just under the hide of the off shoulder.

Nice buff and Waterbuck is super Ed!

None that I could find, The standard 1-12ish twist of the .375 seems to handle everything I ever threw at them. My .416 Rigby has a 1-16" which was lots on paper with the 400s but not so great on meat.

What Rigby do you have? The early ones were reportedly 16+. From what I've read, most new ones are 14. I've read 16 and 14 on the Ruger RSM, guessing 14.

My M70 416 Remington has a 14 twist and shoots the 400 gr TSX fine.

I saw my bud at church this morning. I ask him about the 400 TSX not having enough twist from the Ruger RSM. His response was it went 50” thru the buff. And on a high bench it would cloverleaf if he did his part. So, don’t think he was buying what I was trying to sell.

DF

My .416 Rigby is a CZ 550. I believe they are still 1-16.5" to this day.

A few years ago "everyone" was losing their nut over heavy weight bullets in the 375 trying to correct some real or imagined problem.

Now folks are advocating lighter bullets trying to chase some imaginary advantage!

LOL!

Not everyone and not by a long shot. When the Brooks' first brought out the TSX (and subsequently the TTSX), one of their main (and valid) selling points was use of their bullets would allow you to go down in weight (thus less recoil), shoot a little faster and flatter and not give up penetration. They tested the 375 and 416 extensively in Africa on buffalo and both the 270 and the 350 in the 416 proved to be more effective at least in their opinion. To support this, years later Ross Seyfried clearly believed that NOTHING killed buffalo like the 416 Weatherby at 2700 plus, once again, at least in my view, given proper bullet construction, speed kills.

Agree 100% with Jorge here.

I have used 200gr GS Custom bullets in my .375 for the last 5 years or so. They are travelling at around 3100fps. I can assure you from many samples of Buffalo that we have hunted, that I have yet to find a rifle that kills them as quickly as that combination. The rifles used has been from standard .375 loads to .505 Gibbs. There is no doubt that the high velocity devastates them.
Standard loads on lung shots, all expire at around 60-70yd mark. With the 200gr bullet combo, we find them within 15yds from the initial shot.

I think the 270gr Barnes is a terrific combo for the .375.

Marius, thank you for your input. I always enjoy reading your posts.

I ordered 200 gr. GS for my .375 H&H. Sounds like an interesting bullet. Have you or your clients used Cutting Edge Bullets? The 235 gr. CEB Raptor groups very well in my NH M-70 SS Express, but I haven't shot anything with it, yet.

Why don't we see and hear more about the 250 TTSX? I know the 270 TSX had a head start and has an excellent reputation. The 250 TTSX has a better B.C., shoots a bit faster. If the 200 GS Custom penetrates and performs that well, why not the 250 TTSX?

Dirt: Those Raptors are fantastic bullets. Lots of data and results over on the AR forums
