I noticed that palmetto state armory has some good prices on cases of .223, 9mm and some other calibers of ammo that seem hard to find. The best part is that they are super cheap on shipping. I posted direct links below for the .223, 45acp, and 9mm ammo. If i remember correctly the shipping is $12 a case, and since they are out of state you don't have to pay any sales tax. Hope this helps some of you out.
