A buddy of mine bought one from SSK and I have loaded some 450 grain Barnes softpoints in it as well as 300 grain Barnes and 650 grain 50 BMG bullets. The BMG bullets definetely have a shove when they go off. The others are actually not that bad but terrible on the other end. We have taken it hunting several times but haven't taken anything with it yet. Neat gun though. His is chambered in what I think is a 13-14" Encore barrel and has a fill gill style arrestor brake on it. GS
