It also depends on where you intend to shoot them. If you think it will mostly be shoulder area vitals, the TSX/GMX loads will work fine, although they lean more to penetration and less to fragmentation (pigs likely to run if bone isn't hit). Another option is the heavier-weight cup/cores or bondeds like the 65gr SGK, 77gr TMK, and various Fusions and Gold Dots. They'll work well on shoulders and necks, as well as softer tissue. Varmint-ish loads and FMJ works also, but you better stick to well-aimed hits in the neck/head. I generally keep my truck/buggy AR loaded with the 77TMK or 65SGK, but I'd probably pick up some the Fusion or MSR loads if shooting factory. The Barnes really needs to hit big bones to be most effective, at least at AR15 carbine speeds. My two cents.....
