No real argument guys. Just having trouble with the premiss. On a pure PG hunt, particularly in someplace like SA and much of Namibia, I have no doubt that a 250 gr TSX from a 375 will kill anything encountered decisively. Just not sure why anyone would want to burden themselves with such a heavy piece of artillery when a 180gr .30 would do just as well. (I personally like a .33 but it is not necessary). Different issue entirely hunting PG where DG can be encountered (Caprivi, Zim, etc). In that case I want my PG rifle to be able to get me out of trouble, and I think that is where a .375 shines.....particularly with a heavier bullet.

BobinNH, is correct 20 grains difference in weight of a quality premium bullet is no big deal at all. 20 grain ain't no deal breaker

This is true....which sort of surprised me the first couple of carcasses I looked at. Not what I expected...heavy muscles, but light bone structure is what I thought.

You are correct about bear structure, but when enraged, they soak up a lot of non CNS hits. Head shots were the norm for me when cleaning up a clients botched shot placement. It sometimes ruined the skull but it always put them down, and in the thick stuff, that is what is needful.

A 250gr 338 TSX will arguably outpenetrate a 300gr 375. A 270 TSX pushed as fast as I can get it is about as low in bullet weight I want in a 375. If I drop to a 250 I'll take a 33, preferably a 340 at the speed of heat. jorge

+1. I love my 375Wby but it's for 300gr bullets. The lighter stuff is better handled with a big 33 if a guy has one.

Yes, but you can't generally use a .338 for Buffalo.

I'm suggesting that the 250 grain TTSX may be a fantastic all-around African bullet because it's suitable for Buffalo and exceptional for heavy undulates. Except for those going for elephant, this bullet may do nearly all of it and do it very well.

I don't know that I'd say the same for either the 250 grain .338 or the 270-300 grain 375 -- though I personally had good success on PG with the latter. I'm not trying to overstate the utility of their new bullet...just theorizing.

I just cannot see the advantage of dropping below 270, that 270 TSX is magic and shoots flatter then the 30/06.

Not sure what is gained by the drop of 20 more grains if weight. Certainly the shorter bullet will have the disadvantage of stability over long range and a lower SD if that sort of thing is of interest to people.

The 270 Swift Aframe out of the 375 is the most devistating and consistant killer of PG I have ever seen in nearly 2 decades of hunting as a PH there. The TSX at 270 is even a better penetrater, has been more accurate( marginal) and has taken lots of Buffalo with exits.

I suppose the 250 will be a fine choice, but my biased opinions over 20 years now are causing this doubt in a change. I would like to hear back your results, but seriously doubt that on PG there would be a difference at all, and when you start with 1500lb game I doubt it will be equal.

A couple of things where it could be a plus although these would not be applicable to your use. If Reloader 15 is not available or won't shoot them a 250 grainer will do better with Varget or 4064 burn rates. And there will be some 375s that will simply shoot better with 250 grainers than 270 grainers.

Would also be nice in a 375 Wby or 375 RUM as either would sail over the magic 3000 f/s with 250 grainers. The SD is the same as a 168 grain 30 calibre.

Lower BC, certainly but how can it have a less stability over long range? By being shorter the 250 will be if anything better stabilized shot from the same twist rate barrel as the longer 270 grainer.

SD is not a primary factor in penetration as other factors are. I doubt that on game that there would be very little if any difference in penetration.

I can't wait to try them. I used 235 tsx's in Namibia last April w/ great success. I expect a tipped 250 to be even better!

Good point about powder burn rates, Mike. And the fact that some 375's will shoot a 250gr more accurately than a 270gr......that customised Ruger RSM of mine was one of those smile

And an extra weight being available is always nice to have...........

I have been using my 375wby with 250gr Barn's X bullets for a number of years in Africa. From Impala to Eland.
My Rifle likes them and if its not broke don't fix it.
I shot an Eland with a 250gr X bullet @ 178yds through the heart, it fell straight over, stud up staggered for a second and then went down. When we skinned it there was a hole slap bang in the heart and the bullet was recovered from just under the skin.
The fired bullet still is 250gr.
I don't think I would use them on Buff.....thats what I am bulding my .458Lott for. But as for my plains game rifle , to me I wouldn't change a thing.
But saying all this , they may not work for your rifle.

The tipped version in the .375 H&H, and with an additional 200+fps should be a devastating hammer on game.

Bob...I will take those 30+ year old 250 BBCs off your hands...so you can try the new Barnes TTSXs...from what I read those Barnes TTSXs will work better..... grin

I know this is an Africa forum, but I was hoping those that have knowledge w/ the .375 will answer this.
I am very fond of the TTSX's in all my rifles. I recently purchased a .375 HH that I was going to take w/ me as a back up rifle when I take my boys or friends out to hunt black bears. The only reason for me having this is for the rare (if any) occurance of running into a brown bear on my way into/out of the bait station.

Would you recommend the 270gr or the 250gr TTSX that may open a little faster?
