That is true. I know Elmer Keith blew up some guns and I would assume he was looking for pressure signs as well along the way.
But that's why I was asking about seating the bullets out longer. If I were to do that, then wouldn't that reduce the max pressure, while at the same time allowing more total powder for a longer burn time and increased velocity? I mean is there any harm in seating your bullets out as far as your cylinder length will allow?
