Pull those reloads apart and salvage the bullets. Start with new brass and see how the bolt closes on a new case w/o the bullet. It may be headspaced just a touch on the tight side,nothing wrong with that if you have brass dedicated to that rifle/chamber. Once you have brass fireformed to that chamber the problem should go away. If the reloads you have were not fired in that chamber and were neck sized or not completely full length sized it is doubtful they would chamber right. Also check the case length,they might need trimmed.
