Surgeon 591 WSM action, Remmy trigger... Fired round, released bolt, no stick, no stuck case... with bolt in "Up" position, it will slide back 1/8", and is obstructed by something very stout. It feels like the lug hasn't cleared, but that seems physically impossible... I'm guessing something to do with the cocking/trigger mechanisms? The bolt cocks, and the trigger functions.....?
