I took my Savage Mod. 11 to the range yesterday. Every third of forth round chambered, the trigger would lock up. I noticed that the bolt latch would click and pop up just a hair, then the trigger would be locked up. I could raise the bolt handle and close it and the trigger was fine. This could be a real problem if I was staring ole Wiley in the face. Any ideas why this is happening? It will do it on an empty chamber as weel as live round.
