No lead bullets. My problems are with 125 gr. Nosler BT and 150 gr. Sierra Game King .308, in .300 AAC and 7.62X39, steel jacket. The Chinese ammo is sealed, requiring more force to dislodge.
Today I tried stoning the collet interior. Had some of the Sierra GK loaded and tried again. I could not detect a burr before stoning the collet, but there must have been a slight one. There is no longer a ring on the bullet, but it still sticks. I loosen the collet, push the round in to where the case bumps the collet. Turn the stem to where it is just starting to tighten on the bullet. From there it is about 1/16 of a turn to when the transition occurs allowing the bullet to pull without slipping. After pulling the case down, I loosen the collet and bump the stem down with the ball of my hand. That leaves about .180 of the straight wall of the bullet protruding, the remaining .125 of the bullet is tapered. With this short surface, I cannot get enough grip on the bullet to extract without using pliers.
