Wow! If you don't mind me asking ,what state do you live in? I'm in ohio and we have had Pmags and 223/556 falling out our ass. We have a problem getting 22lr ammo but not 223/556.every week it's there. And they don't let people buy it all either. They let them have 10 boxes or one case or some kind of limit. Ask the people at gander mountain if they can order you ammo from another store or just order it ingeneral. We do it all the time for people who buy guns with hard to find ammo(50ae,500sw,460sw,300blk.6.5grendel,etc......) and for people who don't buy guns we order it. Ask for the "hard lines supervisor" I don't understand why they couldn't order it if you bought a large quantity. We do it all the time
