Received my .40 Super, threaded, compensated Accu-Match barrel for my G21, today. (JR, at Lonewolf was kind enough to have my spare .400 Cor-Bon Accu-Match barrel rechambered)
Fired 15 rounds through my G21 today. 24# Wolff spring and Wolff guide rod; 12.5gr. of #7 (low-moderate load) and CCI small rifle primers. Roll crimped into cannelured, 160gr. WC plated bullets.
It's raining, so I didn't do any chrony work, but est. vel. is 1275fps or so. Could have easily used the 22# spring with the compensator; however, would think that the 24# spring would be needed for factory hot loads or my reloads done hotter.
Will post additional results of reloading/testfiring. Will try to get some chronying done soon.
Initial observations are great. No bulged brass, primers rounded, etc.
