How have those of you who have used/seen both used, come to feel about one vs. the other? -Do they both deliver similar destruction/wounding and open just as quick, or is one more "explosive" than the other? -Do the TSX rounds foul more? Less? -Does one tend to shed more petals than the other? -Accuracy comparison? For me, comparing 55gr GMX and multiple TSX bullets in 5.56, I have noted that the 70gr GMX sheds petals almost to the point of un-usability. The bullet tracks terribly, often veering off in random directions. This is having shot water jugs, and pork with it. I like to shoot random things before shooting game. It also includes shooting water jugs at 100 yards to reduce velocity a bit. The round still lost almost all it's petals and wouldn't track. The 55gmx was the opposite. Beautiful expansion and weight retention at 25 and 100 yards, tracked like a laser. The TSX bullets are accurate for me, as are the GMX. I am shooting 10-shot groups in the 1.5 MOA range, and 5 shot in the 1 MOA range with the TSX. However, when I have been shooting TSX for a while, and then switch to GMX, or SMKs or some other bullet, I get a bit of a shift in POI for the first shot or two, and the same happens when I switch back to TSX. I DO believe there IS some merit to "TSX in TSX guns, Gilding metal in gilding metal guns", as the fouling DOES seem to affect my accuracy. I have not shot either into game, but friends of mine have, and really like the TSX. The GMX is like the dark side of the moon, although it's much cheaper...I am looking to learn more about it "in the real world".
