Dear DHTP,
Had one in for blueing awhile back and it "seemed" like all the rest[$%^&^&]The feeler gauge should be between .003-.010 when put between the forward end of the breech bolt slide and the head of the breech bolt lock. Remember. The action can be damaged if no clearance exists and if over the .010 it is NOT full locked!! To adjust[hammer in fired position] reach through the cocking gear pin hole with a small punch and change the relationship of the cocking gear by rotating to a different position. Easier if you work the lever open and closed a bit too. GOOD LUCK my friend. It is trial and error as I am sure you are aware of. This is the reason I charge a bit extra for the blueing of these lovely rifles[?]
Aloha, Mark[in Or]
