[QUOTE="AJ Peacock, post: 285959, member: 4885"] So please explain how slower powders maintain higher pressure longer than faster powders. If the combustion was complete at 2", then the only thing the pressure could do would be to drop in direct proportion to the bore size as the bullet moves down the barrel. This is the question you haven't answered. You also didn't respond to the quote from the book on Gunpowder, or why every manufacturer lists their powders and their relative BURN RATES. If you were correct, I could load bullseye in my 338AM, and get the same velocity that I get using 50BMG, because for the last 30" of the barrel, nothing would be happening with either powder!
