I may be coming into a couple of spare cylinders for my Pietta NMA. What are the pros and cons to pre-loading cylinders? Can loaded, un-capped cylinders be safely stored in a controlled environment for any length of time? I’m considering a black powder revolver, along with powder, caps, balls, and a mold as part of a bug out kit. Not as a primary firearm, mind you, but as backup for a back up of a back up. And I like the idea of have two three cylinders pre-loaded. But if I’m creating more trouble than I want, I’ll simple load them as needed.
