I recently acquired an M59 Santa Fe rifle, marked Golden State Arms. It is stamped 7.62 NATO. A google search reveals a manual for this rifle, and it states this rifle has been thoroughly tested with all brands of 308 ammunition in all bullet weights.

Should I stick to shooting 7.62 NATO in this rifle, or would commercial 308 ammo work? Also, I have a couple of reloading manuals that have separate categories for 308 service rifle loads. I assume these loads would be compatible with 7.62 NATO, right?

I keep finding conflicting information on this issue. I do not want to destroy my rifle, nor myself, but would like to see how well it shoots.
