ORIGINAL: bigcountry eld, all I could do is look at the appearance. I measured cases I have resized, and compared against. I also notice a very visible bright ring near the base. The primers were much flatter than any I have ever reloaded. And thats alot of 308 ammo. Gut feelings, along with the primers being gold, made me send them back to the person. Maybe they are once fired, but alot of things told me different. Didn't have time or interest in finding out. So I got a refund. And from now on buy them new.
