Years ago I was hunting with my friend. He carried a CVA Mountain Rifle in .58 caliber. I watched him take a bead on a nice fat doe that was playing hide and seek around a tree with him. He touched that cannon off and hit her, square in the face. It spun that deer around and wrapped her right around the tree she was using for a shield. Needless to say we did not put the drag rope around her neck when we pulled her out.
That 58 has impressive power. I hunted bear with only a .54 caliber and round ball. The only thing that worried me was when a mother bear and two large cubs came in. I knew I was out numbered. But never felt out gunned.
