I think that's a good idea, but I'm a little puzzled with how tightly a fired case fits the chamber. It suggests some "sponginess" in the action, maybe. I just don't know about that. But I suppose it could be the ammo, too.

I think Ill measure the shoulders of fired cases and unfired cartridges. Maybe that would shed some light on this.

Don't be the darkness.

America will perish while those who should be standing guard are satisfying their lusts.
