Well 7.62x38R is larger diameter than .32-20

I cobbled some ammo just so we could play. It shot but fireformed extraction was hard. On the second firing they rupture, just too much movement for those brass molecules to flex. I only reloaded 3 that had been fired previously. I slightly thinned the rims too as some .32-20 were too thick for the spring loaded cylinder to push far enough forward to go full cock. An odd duck.

We ordered some PPU boxer primed ammo and I will get the proper dies. Still great fun for a 107 yr. old SA revolver. (Yes this one is SA, not DA) The factory ammo looks tapered to the end but fired cases, the chambers, look like a case with a neck about mid-way.
