you got me.. i shot 1 buck close and 1 at 30 yards neither 1 went in more than 8 inches i dunno if it was just my particular back, but i contacted rage.. they had me send back my 2 used broadheads (i keep all arrows and broadheads as memory tokens) and any of my un-used 1s and sent me my money back.. so great customer service. im gonna use hell razors or slick tricks instead i think
