It has long been recognized that I'm a man of exceptional thrift. So given a couple of buckets of old ammo they ended up on the bench for dis-assembly / salvage / odd lots for the display drawer. I'm down to a couple of inches of old .22's., as I hate to toss live ammo - put the lead in a vice and push the brass off, lead in the smelt pile...
Anyway, I've a whole series of .22's that are powderless. The internal rim area is coated with a green compound, but no powder in the brass. The base is marked only with a 5 point star.
Probably pretty common, but I'm usually well behind the power curve- any input???
