trying to decide between buying a 500 s&w or a 45-70 bison bull from super six co. don't have the ballistics in front of me at the moment, but could anyone tell me how they compare, or if anyone has any experience with the bison bull six shooter. i already have a few 45-70's and do like the cartridge, in rifles that is. won't be till the spring but, it never to early to dream, right? i have shot the 500 smith in a four inch several times. it was cool. but a 45-70 six shooter sounds pretty cool to. wouldn't mind hearing some opinions.
