I have been a Barnes user since 1992, in fact, they are all I use for big game, and also in my 22 Hornet for coyotes.
They seem to 'upgrade' the cartridge being used, when they hit game. For example, a 243 works more like a 25-06, a 270 like a 300Win, the Hornet like a 223.
Way back in January/February of 1992, I was reading an article about reloading the 223. The author was the first guy in the U.S. to get hold of a .22cal X bullet, as the first years production of them went to Australia.
What caught my attention about the X, was when the author shot several x bullets into ballistic gel blocks, and the blocks expanded so violently that they knocked the adjacent block off the table. He shot the X out of a Contender, at about 2,600fps MV, about what my Hornet did (pre-Lilgun). No other bullet, at normal 223 speeds, could do that.
So, I bought a box of 45gr X bullets for the Hornet, and noticed a reduction in the runners and floppers I had (coyotes), compared to any other bullet I tried.
To this day, I use the 45gr XLC's in my Hornet for coyotes. When I run out of those, I'll use the 45gr TSX.
