Fairly good deal on 500 loose US Mililtary Green Tip NATO LAKE CITY M855 (2013), .223/5.56 62gr, for $375. Free shipping. I ordered 2 cases. Not as good as all the cases’ prices I bought since 2002, but that was then; this is now.

FYI.
I think .22LR must be less profitable for the ammo mfg companies so there is not too much incentive for them to try and keep up with demand for it right now.
