Ummmm........ Yeah, I love revolvers and shoot a 460 mag on a regular basis, but I'm with the others that say this is stupid. If a revolver NEEDS a muzzle break to make it controlable, then get a rifle. If the gun weighs 13 lbs., then get a rifle. If you are actually planning to kill an animal that requires this powerful of a gun, then get a rifle since I don't want to be within handgun range of any animal that is that dangerous. If the gun can't be fired one handed by the shooter, then get a rifle, because if it's that heavy and recoil is that strong, what's the point?
I know the long barrelled hand cannons (460 and 500) serve a purpose in "no rifle hunting zones", but I think those are stupid too. Sorry. JMO
Finally, if you feel the need to wear a motorcycle helmet while firing a revolver, then save the money you spent building the utterly useless gun, save the money you spent on the ammo, save the money you spent on the helmet, and find a good therapist........ and then a rifle. Again, JMO. I believe in the saying "Just because you can, doesn't mean you should."
