You may have to get the inside scoop on the delivery schedule for a nearby store and wait it out. I saw 980 rds in a metal ammo can for sale $980 at LGS, 55 fmj and possibly reloads. Another LGS had PMC 55 fmj for $14.75/20 rds, it would better to reload and start stalking up on supplies.
Remember the battle of Athens, TN!
