When I hunted bear with my .54 caliber Renegade I used REAL bullets, but the twist allowed that. Although one day I just loaded up 90 grains and a roundball. I never found a good bear that year.. well I take that back, there was a sow and two cubs and she was a big sow, but that's a no no. And there was one little bear I could have shot but he was too small for what I wanted. We hunted over baits.
