That defect is very rare, and should be the last thing you assume.
How old or how much have been shot through the current orings? Relube or use a new lube as suggested. It's likely an oring or two needs to be replaced. First one to check is the smallest oring that goes around the stem of the bolt.
I had the same issue before, and all I did to fix it was replace the 3 breech orings (since I didn't have the TechT sized orings available at the time).
