Gave in and bought a case of the Czech ammo. Green lacquer case, 1963 vintage. I'd buy more, but I'm lacking the rifle. I don't mind stockpiling (a bit) but I have to be somewhat realistic. Although, since they are canned, they should last forever (and a day).
I saw a few M44's, $169, but Chinese. Bad condition stocks. Seemed pricey for condition: from what I've read, Russian M44's saw little use, and are in generally good shape, while Chinese... isn't. From what I've read, the M44's don't really recoil worse than the 91/30; shorter barrel, so they tend to flip up a bit, perhaps, and certainly much much louder. If I got one I suspect I'd pay whatever for some brass cases and make some handloads at significantly lower power. That or look into pulling bullets from milsurp ammo and taking out 10% or whatever. The M44 did seem like a good size, perfect for a trunk gun--but I already know that I don't mind the recoil on the 91/30--aww, the heck with it, I'll get one of each.
Still no 91/30's. Bummer. I might have to just be willing to pay whatever when I see one.
