A friend shot 120-130 coyotes this past season with a 22", 22-204 ruger, X caliber 223 Rechamber with the 53 Vmax at approx 3600-3650 fps, amazing results. He is an experienced caller/hunter and has access to a ton of bullets and calibers. He and I share a 22/204 Ruger reamer with .020 freebore, no turn neck. We both are getting amazing accuracy with speed out of our 12 twists with the 53s jumping .020 from the lands, IMR XBR 8208 with cci BR four primers, and Winchester brass.
