last time I was in the local walmart they weren't having any problem at all moving ammo. The only thing I saw were some shotgun shells, and about 20 boxes of various hunting rounds (.243, 30-06, 25-06 etc.). All of their pistol ammo was gone, all .308 and .223 gone. Pretty sure if they got it in, they could move it.

not to mention some of the most common ammunition in the world is .223/.308
