I would be in for .223/5.56 and .40
Given all my previous experiences with the group buys you have organized, I am more than confident that the price would be right.
I'm keeping an eye on it to get an estimated volume. I think the calibers are pretty solid with .308, 9mm, .40, .223/5.56, with a maybe for 7.62x39 (it's not because of interest, but I don't think I'll be able to beat current deals that abound)
As for the '06 (garand compatible) that's probably not going to get any better than surplus you can find elsewhere. '06 standard rounds are a maybe.
What deals are can't you beat on 7.62x39. I'm not being condesending. I'm serious. Give me a site so I can get the best price from a reputable source please. Anybody get some recently for a good deal?
