How exactly do the replacement cylinders for blackpowder revolvers work? I have seen them in Brownells, and MidwayUsa, and they look to be a two piece affair with individual firing pins for each chamber, but do I have to disassemble my revolver each time to reload it or do they have an integral loading gate? I have heard that the tolerances are tight enough that some brands of .45 colt ammo won't chamber properly.
