MAB, that is probably your best choice. In a situation where there is wear, the headspace will become "greater". Bolt will go to battery but too much room in the cylinder. I don't think it is a headspace issue at this point. More a problem with debris in the chamber/throat. Way to check:
1) does the bolt go to battery when no round is in the chamber?
2) if yes, you may still have too much debris in the chamber/throat such as plastic, etc. That can keep a round from completely chambering, thus keeping the bolt from going to battery.
If the bolt will not go to battery with no round present then the problem is in operating system/locking lugs
