While at Ohio show, I grabbed a box labelled “7.62 Takarev” (misspelling is on the box) because it was cheap, a couple of $$, I was in a rush and had no time to look at what’s inside. I got back to the hotel and found unfired 9x19 blanks with a headstamp ZV 61 instead of Tokarevs. That is a reason I like gun shows, I can still tell between a Tokarev and a Luger, and it makes me feel like an expert.
If they have a ridge/shoulder cut up near the crimped end they’re 9mm, if rounded without the cut, they would fit a Tokarev. With that date they should have the cut.
