Barrel gap

On my Pietta's, you can bang on the wedge until you're happy with it, and it isn't going to make any difference. But on the Uberti, if that thing gets more than a light rap with a screwdriver handle, I can't spin the cylinder. The wedge must be just lightly tapped snug and even then I take a box of Baby Wipes with me, because after just 6 shots, the cylinder face must be dressed up a bit before the next round.

Doc, I have wondered that same thing. I have found in my chart (Black Powder Handbook-Sam Fadala) that bp spikes almost immediately in the burning curve and then falls off a bit, and then has a long smooth burning curve. 'Not sure how far the bullet has moved before the pressure spike starts to fall off though.
