I know some guys in La that did a group buy on ammo from them. $7k free shipping. Group by lasted 6 hrsSGAmmo.com had a screaming deal yesterday (that I was lucky enough to get in on!).
$289 for a 1,000rd case of Prvi Partizan M193. I think the owner said they would be selling more cases as the shipments come in but from my experience, by bulk and you will save lots of $$$.
Here's another deal: Widener's Reloading and Shooting Supply INC
^ Best M855 you can buy.
