7.62 M1 Garand sticky chamber

[Chuckindenver]

its been my experiance, every time iv tried a washer, even a thing brass or copper one thats thinner then paper, it was unsafe, on square threaded shouldered barrels.
the only square threaded barrel its worked on, is a Krag, as it crush is at the breach face, and a rimmed case.
i can relate to the less money, more time thing...
