As it turned out I ended up shooting about 60 buffalo and about an equal number of pigs with that combo, and none of them asked for a refund. I ran it past Barnes for fun first, but they were sure interested in my results afterwards.

You could do well with that bullet in North America if you just want to use your rifle. Never mind that you wouldn't be better served with a 300 Win, or 350hornadys in your .458; it'll work just fine.

This coming from a guy who doesn't even like barnes much. wink

I've made reference to Model 70 Guy's results a few times ln my blogs, as well as from personal tests in tough mdedia compared to several other bullets at impact velocities simulating 100 yard impacts from a .458. The 350 TSX (two fired) completely penetrated the test media (15.5 inches of hardcover books and dry glossy magazines, plus 2 planks of wood, 1.5" each). To compare with others: the 350 Hor lost its core and penetrated 4.5"; the 500gr Speer African GS made 6.5" and lost it's front core, retaining 310gr (one of the 350 TSX was stopped at the last panel of the last box with a penetration of 15.5" and 100% weight retention). Several solids penetrated completely. But the 350 TSX at 2750 fps MV impacted a bear frontally at 100 yards and never expanded according to a best analysis. It was a smallish bear where the bullet made exit in the right flank and the bear ran in a semi circle and expired forty yards behind the bait. I've killed lots of bears with .45-70s and .458s, and that was a first. The bullet is very tough and needs both speed and adequate resistance for expansion. I've no doubt it would be great on game like bison and big bears. As Ron said, it's also very accurate using H4198.

That's about what I expect from TSXs or any other mono bullet. If you don't want your animal dieing someplace else when you're using a mono break something that is holding it up.

Life begins at 40. Recoil begins at "Over 40" Coincidence? I don't think so.
