sportsmans guide for 7.62x39
ammunition store for most other, anything you buy from ammunition store you can believe nobody will have it for much less if at all. If you do not want to shop areond you cant miss with ammunitionstore.
the only other consiteration would be shipping, if you are very near a supplier maby you could pick up ammo and that may make some other place cheaper.
hope it helps
wally's, for most stuff, but I long ago went past the need to shoot much centerfire stuff. Realistic defense just doesn't require it, and the .22 units save me a lot of time and money. A suppressor on the 223 auto makes it handle exactly as does the unsuppressed .22 unit, for fast work inside 75m or so.
is quite easily achieved with an AR-15, electronic sight, and a bit of practice with the.22lr conversion unit. Of course,what matters is the times-hits with 223, but the AR is so tame that I've yet to post a time for hits on target with the .22lr that I couldn't readily match with the 223 parts installed. Most guys can't reliably hit the first torso in 2.5 seconds, with iron sights, anyway. I've seen plenty who missed quite frequently at 50 m, trying to move that fast. Starting from low ready, including reaction time, on an electronic shooting timer. Targets being 12"x24", 5m apart,edge to edge.
