I have 600+rounds of Rem/Umc 55grn on 10rnd stripper clips, $230. This is brass and reloadable. Also have a sealed tin of wolf performance, 500rnds 55grn for $115. 600 rounds of igman 62grain for $380 in can.
Someone had mentioned you might have some .223 either Factory or Military Surplus at decent prices, if this is true what would you be asking for standard amounts, IE 240, 500, and 1000 rounds of .223
