I have 5.56 and .223 ammo on backorder at about .40 cents per round through a popular online retailer. The fill dates are tentatively set for late October and early November, and so far haven't changed. What are your experiences with back orders? Are the orders being filled, or continuously pushed back further, or cancelled? I am not hoarding, just hoping to not run dry so that I can continue occasional target shooting with my sons.
