Joe,
I buy a lot of 7.62x51 surplus for my .308 HK91, usually runs 38¢ to 41¢ a round, delivered to my house.
Good surplus from Malaysia, Germany, and S. Korea. Mostly from the '80s.
At that price, I can afford to shoot a lot.........
.
Peace is that brief, quiet moment in history.......... when everybody stands around reloading.
