Don't get too excited about the price; I've not had good results with this ammo. From what I can tell it is Syrian and 7.62x51 from the late 50s or early 60s. If you reload, maybe you can pull the ammo down for components. I get primer strikes that don't fire the round and sometimes it doesn't chamber smoothly. I was using it in a 308 Savage bolt rifle, which might be part of the problem, but I won't take the chance of shooting it in one of my semi-autos. You get to choose for yourself if you want to chance it, but I think breaking it down for components is best.

I don't know how many boxes I have, but it's a couple cases.
