Vast majority of 99's were 7.7, but it would be best to have this confirmed by a gunsmith, if you can't tell. Ammo is available from Norma; it is also not hard to find components for reloading either.
My buddy at work has a buddy that is a gunsmith... I'll think I'll let him take a look-see at the rifle before I do anything to it... As far as the safety, I'm not exactly sure where it is. I have the weapon completely disassembled at the moment. If it's the round piece about 1.5 inches in diameter on the back of the bolt assembly, then it is knurled...kind of in a spiral fasion ?
I'll take some pictures of it tomorrow and post them to my gallery.
Thanks again !
