I've noticed that the "big box" stores get looked over. I do refrigeration service for Walmart, everytime I'm in store I walk thru sporting goods to see what they have. 3 weeks ago I found 420 rounds of federal 556 on strippers clips and I've been getting 22 there to. Most every store carries 30-30, 30-06 22-250 and 7.62x39 with a decent stock
