They're good, fun guns. I, myself own a MAS 49, but I've been looking for a MAS 36. Both shoot the same 7.5x54 French.
Prvi now loads for it, have been for a year or so. I bought 2 boxes when I bought the gun (within the last year). I don't remember the price, it was all part of an out-the door price. AIM Surplus usually stocks it, for around $12 a box, give or take a little. At the Atl. Gun Show today I saw some loaded by PCI, their Jap ammo is pretty decent, and a lot cheaper than Hornady or Norma. The dealer wanted too much for it though, $23 a box IIRC, so I let it pass. And lastly, Hornady's metric line of ammo probably has a load for it, but don't qoute me on that.
Anyway ammo is out there, but it's hard to find in stock at a store. Many stores will get several boxes in if they get a rifle for it. Other than that, few will stock it. And it's always cheaper at AIM.
BTW, what was the gun listed at? Most I've seen, in very good condition were in the ballpark of $350.

ETA-Never mind on the price, I just pulled up the pics and saw it. Better than average price, and a good looking gun. It probably would've followed me home if I'd have seen it.
