I am not talking whimpy loads or overpressure loads, with your everyday loads you want the front of the bolt to around 1/4 inch in front of the back of the ejection port window, if the bolt is farther back than this empty cases will ding the wing everytime with normal loads.Originally Posted By: GLShooterOriginally Posted By: dennydHow far is the front of the bolt from the back of the ejection port when you pull the charging handle all the way back?
Pulling the bolt back by hand does nothing to duplicate the ejection cycle or velocities. The bolt may go back as deep as possible or just barely enough to get it done.
