[QUOTE="RockyMtnMT, post: 1178612, member: 7999"] The friction between the bullet and the barrel will cause pressure as the powder burns. As long as the powder is burning the velocity will increase along with the pressure. If the pressure drops the bullet will decelerate because of friction or drag inside the barrel. Generally speaking a bullet would increase velocity for the entire time it is inside the barrel, unless the barrel is so long that the powder is burned out before the bullet exits. Maybe I am missing something. Steve [/QUOTE]
