I just recently picked up a nice FN49 in 8mm, and I believe it's one of the Egyptian ones because of the caliber, and because of the numbering system that's used as the part numbers (all matching) and the rear sight graduations. Really only thing wrong with it is it doesn't have the original fixed magazine.
The main thing I'm wondering about this thing is what kind of ammo does it like? I hear it shoots lighter ammo better than it shoots the heavier stuff, but I wouldn't know what brand of ammo it prefers or if anyone even makes good ammo for it. I'm not messing with corrosive surplus ammo because it's semi-auto. I'll shoot corrosive through my bolt actions because they're much easier to properly clean, but from what I've heard cleaning semi-autos is a pain.
If anyone has any experience with these things I'd love to know what ammo to try out first.
