I ordered two 440 round packs of XM855 from a reputable dealer a little more than a week ago. I called them today to inquire about the shipment because I still haven't received it. I got a tracking number that said the package was left on my door step nearly a week ago (I live in an apartment with all sorts of people walking past my door). Obviously the ammo has been stolen. What's my next move? Do I contact the dealer or UPS? This sucks. There's a thief out there with 880 rounds of my ammo.
