Dan:

I certainly hope you plan on fireforming some of your own brass....what good is the gun if you aren't going to shoot it!

Seriously, save your money, don't buy brass for a $1 a pop (unless its NE calibers, then buy all you can and resell!).

Buy whatever brand ammo (loaded, in normal 280) you want to use. IE: If you want to load in Rem Cases, buy some inexpensive Rem Core Lokts.

Everytime you fire one of those loaded rounds, it comes out fireformed to YOUR exact chamber. Sort of like a magic trick what?

Not all AI chambers are EXACTLY alike. Which is why I have always been told by my smith not to shoot ammo fire-formed in a gun other than mine. Just passing along what I do, and what I have heard.
