I have a thompson/center hawken thats 50cal.I shoot 80gr.pyrodex to 90gr. with a 350gr.thompson/center maxi bullet with the lube in the groves.Is this a resonable powder charge and how high of a powder charge can i go?I shot one 6point buck with it at 40 yards,perfect behind the shoulder hit,and the buck ran for 125 yards like nothing ever happened?Is this normal?I got total penetration but sure had to track & drag a long ways up a mountain......How much powder do you guys load for 50caliber?
