Thread: tight closing the bolt

Looking back at it with fresh eyes after your statement it sounds like it was a combination of under-lubing and super hard / springy Winchester brass. Interesting.

rereading this I did think at the time it was because not annealing and an inconsistency in stiffness of the brass
lube helps tho
