Years ago, I had a CVA big bore mtn. rifle, in .54 cal. I took it on 2 different hog hunts in Tenn. Killed a hog on both hunts, each was a one shot kill. My load was a .535 roundball, .010 patch, and a 100gr. load of FF Goex black powder. In addition, I killed about 15 deer with that gun, and a doe antelope in Wyoming. Go for it!
