Wal*Mart
I can pick up .223 (Rem) at Wally World all day long for $5.43 a box (that's 27 cents); the Federal bluebox (HP) stuff is . . . about 26 cents.
I can (sometimes) pick up Federal red box (FMJ) at Sportsman's Warehouse for $5 a box (25 cents).
So far, I haven't found anything I can order by mail that will save me significant bucks after shipping (and sometimes "membership") is factored in.
If anyone knows who can get .223/5.56 shipped to Nevada and get it here FOB for under 23 cents a round, I'd be interested.
Right now, I can stock up incrementally for a few bucks a week. If I could land 1k for under $220 -- to my door -- I'd be a little ahead.
Couple of guys I work with scored gun show bags for about 18 cents a round. Trouble is, it wouldn't feed in their ARs. It MICed out all over the place.
Once summer comes, this is going to become more important.
Some kind of disease of attrition affects my ammo stocks during the summer.
