x39
I have not shot the Hornady SST x39 load (its 125 gr as I recall). But.......I think it would be head and shoulders above the import hollowpoint stuff on game. The comparison of the x39 to .30-30 seems apt to me and I can't imagine a hog or small whitetail surviving a well placed round.
Bamaboy and myself have killed deer with the x39 in a Ruger 77 and a Mini-30 w/ no problems using W-W 125 SP or a reload using a now discontinued 135 gr SP (the pity).
