i threw this one out to the gang over at marlin leverguns but,so far, no takers. i have an old 336a with a 24"barrel. i'm just wondering if, with the right powder, it would shove a 180 grain r/n bullet fast enough to make it expand at a reasonable distance(100-150 yards) on a tough target. like elk. maybe the 170 gr partition is the answer but i can't get the 180gr out of my head. thanks fer listenin', dinger
