Reloading 223 for a AR

[LariatBob]

I have loaded countless thousands of 223 on my Dillon 550B using standard Dillon dies. Of late I have been using Hornady 1-shot spray case lube and it works fine. Fired all that ammo in several AR's, no problems.

+1 on the Hornady spray. I like it because it works fairly well and won't kill primers.
I also use a Lee collet crimp die and slightly crimp the neck.
