[QUOTE="CliffM, post: 921560, member: 11533"] The best I can figure is that after the powder is burnt the gas created is still expanding with enough pressure to keep the bullet accelerating. On the pressure curve the peak pressure(64400psi) occurs at about 2-3" down the barrel, 95% burn comes at 13-14". At 26" there is 20000psi, at 30"-13400psi, at 33" (where this load reaches 100% burn) 12300psi, at 40" there is still 10200psi behind the bullet. Cliff [/QUOTE]
