I reload my ammo for my carry sidearm. I load 158 gr. XTP over 5 gr. of Unique for my .357. The one thing that I do different from my other reloads is that I seal the primer to prevent moisture from getting in the cartridge. I put a film of fingernail polish in the primer pocket and then set the primer while still damp. This film must be kept thin so that it will not seal off the primer hole. It is a good way to identify my carry loads as they will show a red ring around the primer. (Red fingernail polish, that is.) My one wish? I hope that I never have to use this cartridge on anything but a target.
