The 270 TSX has such a following, I guess the newer 250 TTSX is the step child.
To me, the 250 TTSX makes a lot of sense, better B.C. for a long shot and classic Barnes penetration.
I'd have to give it a serious look if going for buf. I've read some accounts claiming the 270 TSX is more accurate. I'm gonna try them both pretty soon and we'll see what my M-70 has to say about it.

Huh?
B.C.'s: 250 TTSX is .424; 270 TSX is .326.
Barnes tops the 270 TSX at around 2,800+ fps. They don't currently have data for the 250 TTSX on their web site.
Surely a 250 will fly a bit faster than a 270 out of the same gun.
Higher velocity + higher B.C.'s = flatter trajectory. Both will penetrate and kill stuff.
Just saying.

I get all that but I thought you (we?) were talking buffalo where a 100 yard shot is long?
I understand.
I'm not a buf hunter, probably never will be.
Just Loony stuff, but one would have to show that the 270 TSX will out penetrate the 250 TTSX, and it may, to make a case for it over the 250. There must be a trade off somewhere between the extra few ft. per second and 20 extra grains of bullet.
If I was facing a buf, I may go with the 300 gr. A-Frame as suggested by another contributor. I've read some accounts on .375 300 gr. NPT performance to suggest that the A-Frame may be the best of that type bullet.
The 250 TTSX should be a good choice for all around use, not excluding a buf.
Just thinking out loud...
