On somewhat of a parallel note: my father in law had a semi auto 22 that he finally handed down to me. He had a 10 shot clip for it which he had left loaded for a few years (not sure just how many). It won't shoot the last 3 cartridges anymore. The clip spring won't push them up with enough force for the receiver to catch them.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
