Lew - I mentioned that the bullet could have just been kicked around, and I agree that the case doesn’t appear fired and then reloaded. The primer cup looks right, and I can see no obvious case head expansion (most dies never take the entire base back down to the original diameter, but rather just bring it into chamber specs) and no ejector mark. However, and this is NOT a judgment of your round - I don’t know what it is - but a reload doesn’t have to be made with a fired case. Some real experimental cartridges made in tiny lots (and plenty of fakes) have been made by taking a box of ammo off the shelf, pulling the primer and dumping the powder, and starting again with different powders and bullets, or whatever the nature of the experiment was to be. They are very hard to identify as reloads when done well, and if in cases that have had little or no crimp - friction fit bullet seating - they are near impossible to tell. I have taken apart some rounds from my collection for various reasons, and reassembled them and would defy anyone to tell it. I never do this with stab-crimped or heavily roll-crimped rounds, as the pulling of the bullet ruins the crimp. Of course, when possible, I use duplicates to find out what I need to know, and just scrap them after unless they are really good ones. But, I apply the same rules to good ones. If they have a crimp that will be ruined by bullet-pulling, I don’t do it.
Regarding your round, I can’t even tell what load it is supposed to be, or how the bullet is constructed, from the picture, so I sure as heck am not proclaiming it a fake. I have seen stuff more suspect than that which have turned out to be good. That is true of a couple of 9mms I have that were made up at Aberdeen PG. I had them set aside for destruction but luckily visited the Lab in Tucson before I got around to them, and found the identical pair there, and Bill evidently got them right at APG. I do try to be sure before I destroy fakes, but I have ripped apart my share of them. I still have some highly suspect in my own collection!
