Spec'ed a .20/223AI reamer today from PTG. Called for a no-turn neck with Lapua Match cases and the Hornady 40 gr. V-Max out of the doughnut region of the neck. Dave said a .231nk with .45FB and a 1deg-30 throat is what to use. 6-8 weeks and I will start a new build, Woo Hoo! ;D Chose this as I already have the .223AI dies and cases o'plenty.
