[QUOTE="green 788, post: 629245, member: 3781"] put a couple layers of masking tape, or one layer of duct tape on the case head of one of those rounds that wouldn't fire... see if the bolt will "no go" (failure to close, too tight)... If the round chambers easily with a layer of duct tape on the case head, then you do have the shoulder bumped back too far. If the round will not chamber, I wouldn't suspect a shoulder bump excess... could be firing pin issue, or even some bad primers. Your extractor is going to hold the case pretty close to the bolt face, by the way... so I'm leaning more toward a firing pin issue or some bad primers (at times, primers will have too heavy of a cup, and they're hard to ignite)...
