[QUOTE="su37, post: 287143, member: 5541"] I'll repeat for the last time what was stated and what is obvious. "Even at the correct pressure a tiny bit of powder doesn't burn, 1% or less. But again, it simply isn't going to burn. All the powder that WILL burn is burned up just in front of the chamber. So no, different powders don't ALL burn up within the exact same distance in front of the case. The cartridge, powder, bullet all have an effect, and the point of peak pressure does vary. But the powder doesn't keep burning on down the bore. The gas created keeps expanding." "But the powder doesn't keep burning on down the bore. The gas created keeps expanding." "But the powder doesn't keep burning on down the bore. The gas created keeps expanding." "But the powder doesn't keep burning on down the bore. The gas created keeps expanding." [/QUOTE]
