I hope that your neighbors "really love big-bore revolvers," too, because your home-defense bullets may impact their houses—and maybe their bodies as well.
I think that your choice of guns is overkill, but that's just me.
Your previous posts lead me to ask: Exactly how much pistol-shooting experience do you have?
I note that you've decided to shoot .44 Special cartridges through your .44 Magnum revolver, so I wonder why you even have a .44 Magnum gun.
What're you going to use in that .460 Magnum?
