I use them out of my 280 AI, 300 Win, 300 RSAUM. Farthest shot was 75yds. Two of deer the bullets never exited and they dropped in their tracks, the 3rd was neck shot and bullets did go through both sides but dropped it. No damaged meat on any of the deer. I get great accuracy with TSX, i'm trying the tipped Tsx out of my 280. But i will say that i couldn't get the old x bullets to shoot at all.
