I was watching a hunting show. The guy was using a Hawken rifle with Minie balls. Never said the caliber but guessing about a 54 cal. Can't tell the make but it looks just like my pedersoli. Mine is flint his was percussion. During the show he said I need to get the Moose within 150yds to shoot it. That's seems pretty far to me. So I wonder would it be possible to shoot that rifle that far and still have enough energy to kill a Moose. What everyone thought on this? It very well could be possible. I shoot mine a max at 100 yds but I am going for whitetail with round balls.
