walmart, ive always used the winchester white box brand and maybe had 1 fail in 1000 rounds that i can remember which is nothing to even discuss. its cheap, feeds reliable and really accurate, powder seems to be decent quality since after 100 rounds my guns are barely needing a cleaning but i clean them anyway, ive even used their 223 ammo and works excellent, i have nothing but good things to say about that box, look into federal as well they carry it too-another great bargain and accurate too, stay away from wolf.
