Anyone have any feedback on 223 RCBS AR Series Small Base dies? It is all I have ever used. Before I got into serious reloading, I had trouble with FTF / FTE out of my Bushy AR. Going to SB cleared that up. It could have just been a coincidence. It could have been cheap crappy magazines. It could have been niavete' on my part. Anyway, RCBS now offers an "AR Special" set of dies that comes with their SB FL die. The SB reduces the case body diameter by another .001 to .002 on the diameter over their standard .223 FL die. From www.rcbs.com: AR Series Dies
The new RCBS® AR Series is a must for the progressive reloader. It features a Small Base sizing die and a new Taper Crimp seating die. This combination makes reloading easier for AR-style or semi-auto shooters. The Small Base sizer guarantees that the cartridge will rechamber. The Taper Crimp Seater is more forgiving when various case lengths are loaded at the same time. Case neck crimp bulges and buckled shoulders are virtually eliminated when Taper crimping is used with cannelured bullets. The trade-off? There are potentially two that I see. 1. If you are interested in getting maximum number of recycles out of your cases, the extra .001 to .002 downsizing could reduce that count by accelerating work-hardening of the brass. 2. if you are interested in attaining maximum accuracy as a bench rest shooter or match shooter, or run a .223 bolt gun, the SB could potentially allow a little greater case and bullet misalignment with the true barrel centerline (freebore and lands) due to a sloppier fit in the chamber. |
