TR is that a result of the bolt not unlocking and then the oprod not having anyplace to go with all that energy behind it ?

Ive noticed on alot of the SWC weapons after all the use we put them threw. Thats one of the major problems when the weapon gets hot, is the bolt fails to unlock and extract the round. its got me thinking maybe the bolt and the chamber need a redesign. I know if we make the thing loose it won't be as accurate. But would that solve the failer to unlock if the boltface and chamber where not so tight. gunsmiths got any feedback?
