[QUOTE="emp1953, post: 1819116, member: 71817"] Do you crimp your bullets? If you do you could be causing a neck deformation that interferes with chambering and bolt closure. Do you trim all of your brass? Firing and sizing can stretch a brass case causing this problem. I use a Lyman Chamber gauge. See the attached picture. Out of every 100 rounds loaded I may find one that won't chamber with hard bolt closure. They will fail in this gauge. I pull the bullets, reclaim the powder, take measurements, full length resize the put them in this gauge again, if they still have a problem I measure the length and trim if necessary. I always chamfer the inside and outside of the case neck. Usually I fix what was wrong with the case and it functions properly. If not I put it into a scrap bucket with a note on it. My shooting range has occasional meetings where "anomalies" are discussed. That case will be one of the anomalies. [ATTACH type="full"]172099[/ATTACH] [/QUOTE]
