Most ranges don't allow steel core, ap or maybe even fmj. i've never heard of them not allowing hp.

anyway, i been buying a box or two of 223 when i go to walmart, i get my 9mm wwb from walmart, 22 bulk packs from walmart or cabela's.

i'm probably going to order a K or two of .223 from ammoman for 380+ship (i think thats where it was) and cope's dist. sells 1k of GT 7.62x39 for 180+ship.

natchezss is pretty popular, ammoman, aimsurplus, ammunitionstore.com, etc are some i have bookmarked.
