I have a 54 Hawken project rifle in my safe that was my BP starting tool. I killed many deer with it using Buffalo BUllets and then went to HB Buffalo Bullets. I then found the Lee REAL, Rifling Engraved At Loading, minnies at 200grn and they REALLY shot well!!!! I then began hunting with them over 75grns of Pyrodex RS and they killed several deer before I hung up gun deer hunting for a few years to chase bowhunting exclusively.
I now shoot a 50 cal Knight in-line and use the power belts also. Can't complain about either weapon except to pick a kill spot and drill it.
