I think you`ll have a problem finding a manual not put out by a powder or bullet producer. Even Lee which is a tooling manufacture uses bullet and powder companies old data in the manual they put out. The only other choice that comes close is Lyman.
I`m not sure what is the best manual out today but, all the major component manufactures have new books out (I believe) and as far as I`m aware they all cover the new short mags to some extent. I`d look at the Lyman #48 as you don`t want a bullet or powder co. related book. My personal preferance would be Speer or Noslers simply because I use their data most often now in my own loads.
