So far, I've only tried the TSX in one rifle, my .30-06, but it has impressed the hell out of me. I've shot it at ranges out to 300 yards, and it seems to perform like a match bullet in my rifle (168-grain TSX pushed by 64 grains of Vihtavuori N560). Last year it dropped a large muley buck in his tracks. I'd definitely like to try this bullet in other rifles, especially the new version with a plastic tip, which should make the bullet even better at longer ranges.
I tried the Accubond this year (180-grain out of my .300 Winchester Magnum at a chronographed 3,060). I shot a muley from a lasered 250 yards from a sharp downward angle (down and across a steep ravine). The bullet entered the spine from above and exited behind the shoulder on the left side of the animal. The surprising thing is that the entrance hole was 5-6 inches in diameter and ragged (no exaggeration) and the exit was only 1 inch in diameter, at most. Several of the vertebrae were simply gone. (I presume they were exploded into bone fragments which went everywhere, like shrapnel.) This leads me to believe that the front half of that bullet disintegrated immediately upon impact with the spine. This is a very fast opening bullet, like a Ballistic Tip. However, the rear part appears to have held together, as designed, and continued on.
The downside of this bullet is that it does appear to tear up more meat than a TSX. But, once again, the accuracy of this bullet seems comparable to a match bullet in my rifle.
I'm curious to hear how these bullets hold up on larger game at magnum speeds.
