Sign up for in-stock notification at AIM Surplus. In December I bought a full can of 500 for $586 delivered (shipping and sales tax). That's $1.18 per round. I have quite a bit of LC and HXP from the CMP still, but decided to get some of this "fresh" ammo to have on hand for the semi-auto BAR 1918A3 I just bought.
I am signed up on SG Ammos site. That's how I found out. I too have several cans of HXP and a 520 round can of Lake City. But, I only have about 150 rounds of PPU left. I'd like to get a little more of it.
