Have a new Krieger barrel on order for a 223 AR and have a choice of reamers, the standard 223R, or their match reamer. The first has a 3 degree leade into the lands, while e match has a 1.5 degree transition. The chamber length is 0.060 longer, and is designed for e 80 and 90 g bullets to be single loaded and give more case capacity.
Most of my shooting will be with magazine length rounds, and on my HBAR barrel that had the match reamer, the 69 and 77 Sierra match kings are already jumping 0.060 out of the magazine.
Would I be better with the standard 223 reamer, which will get me a lot closer to the lands when shooting out of the magazine?
