Round balls!are not great critter killers. I just picked up a .50 Hawken flint from a friend that needed money
Other than that, I shoot .54 cal.
Thanks to a gentleman here I came into so.e R.E.A.L. bullets in
50 and .54 cal. I just have not been able to get pit to try them in the TC Hawken and my Lyman Deerstalker..
My best shooter is a TC Renegade with a Green Mountain RB twist barrel. But that 32" barrel is heavy.
