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.
