Riot, read my last post not just skim it. The bolt will be fully retracted, it cant mar the cylinder because it won't touch it.
Didn't skim it. The bolt is not fully retracted until you reach half cock. At least, it isn't on my guns. Trying to hold the hammer just short of half cock while simultaneously inserting the cylinder with the other hand and lining up a cylinder notch while you're doing it, is fine if you have good dexterity. But I don't. I guess some do it your way and some do it the Clint Eastwood way. I prefer the latter, 'cause I can't do it your way without marring the cylinder.
