does any one know what this is? It looks like the 90316 or 90470. One grease groove and a long nosed swc plain based thing. It looks like a target bullet for the 45 acp I shot in the service 40 years ago. I measured the cavity as well as I could and got .435"?? To big for 44 and to small for
the 45. Guess I'll have to wait for warmer weather to cast some for a real measurement.
