Alright MFers, I was going to post a link to my apparently not-so-secret source after I went in a picked up a few more boxes.
Now that the cats out of the bag, ammostore is good to go, and entirely too close to my house to do my finances any good. Best prices on Lapua brass I've seen anywhere. I don't bother looking anywhere else for brass and ammo. If they carried powder and Berger stuff life would be too good.
