I have a pretty old bullet and I cant figure out what it is. It looks just like a .22 LR but its shorter, the rim is much thicker and bigger around. It looks as though it has a copper spray on finish on the bullet. On the bottom of the rim is a diamond stamped in. I think its .22 caliber but it wont chamber in a .22 because of the case is too large. Oh yeah, its rimfire also. Please help me figure this out.
