I picked one of these a few weeks back in the 8&3/4" barrel
Shooting 45lc is a joke ( it feels like a 22lr) then when you get to a 454 it's a wake up call , then throw in a 300 gr 460 magnum and it's ridiculous ( I think it let out about a 2 ft blast)
I thought it was going to be like when going from a 38 to a 357 but it's more like going from a #8 shot to a 3" slug
