Clips can be found at Numrich for like 5$, PPU makes ammo for them now, and being weird, is often the only ammo left unhoarded in stores these days
I had a chance to finally shoot mine recently--totally fun! Rechambering it to 50 Alaskan will be funner, but I just may buy a second to leave as-is. They're actually better project guns than Mosins, since nearly all that are left are in bad shape and "bubba'ed" by the various regimes that mixed/matched, cut them down, and rechambered them. As Mosins are climbing in price, I'm noticing people posting about their M95 purchases more and more--perhaps when the M95 is the cheapest, we'll start seeing more ammo options for us tight-wads.
