shot a s&w 460, just bought a 500

There ain`t much difference. According to my Sierria manual the fastest you can push a 300 gn. bullet in a .45-70 with a 22 in barrel is 2150 fps. I don`t have data for the .500 with a 300 gn. bullet, but it will push a 275 gn. bullet to 2137 fps., or a 325 gn. bullet to 2002 fps. from a 10 in revolver. That would definately mean the .500 was harder hitting. The reason is that it has a higher working presure than the .45-70.
