Posted this in the Reloading forum for the ammo gurus but thought someone here could help as well.

Bought 200 of these from a guy who had 1500 he bought in bulk/loose. Unknown grain or anything else about them other than 7.62x51/.308. Got them cheap figuring as long as they go bang, I could practice with them if nothing else.

As pics show: Casings stamped with "Federal 12" (all of them) and they have a OTM bullet (tip looks like FGMM) that have a groove turned at the base near where the bullet seats in the casing. Anyone know what type, grain or overall quality this ammo is?

Thanks...View attachment 39603View attachment 39604
