With minimum diameter requirements of .45 for deer and .50 for elk, at least that's the criteria here.Get this I hear it's actually legal to hunt big game in some states with patched round ball from a flintlock.
Hunting with barely adequate equipment is like fishing with cheap line. Sooner or later if you keep at it your going to hook a trophy. Good luck landing him with the cheap line. I know, I learned my lesson the hard way a long time ago. You won't find me in the woods under gunned, and I no longer own a magnum rifle, or at the river with dime store fishin line.
Edit: forgot I do have a 22 magnum.
