I was just looking at the ar15.com EE ammo forum and couldn't believe what people are asking for 5.56mm ammo. I've been sitting on some for quite a while, and now that I reload, I'm thinking I should sell some of the mil-surp non-reloadable stuff. I've got a few of the South African battle packs that were commonly available about 10 years ago. Heavy plastic bag, marked: 300 RD 5,56 x 45mm BALL M1A3 O CTN This stuff is brass cased, berdan primed, and M193 equivalent AFAIK. So...the question is, what's reasonable to ask for 3 unopened battle packs? Supply of this stuff dried up years ago, so there doesn't seem to be any on the market to gauge prices.
