Took my 20" Rexus build out to day for break-in and was able to chronograph some loads while I was at it. Velocities were obtained with a Garmin Xero C1. All brass/primers looked great with no signs of excess pressure.
Hornady Black 123 gr ELD Match. 2520.5 fps. 24.2 SD.
123 gr Nosler CC, 30.8 gr CFE-223, Tula SRM primer, New Starline brass. 2.250" OAL. 2515 fps. 20.2 SD.
123 gr Nosler CC, 29.5 gr StaBall Match, Tula SRM primer, New Starline Brass, 2.250 OAL. 2435 fps. 9.7 SD.
StaBall match also gets me great standard deviations in .224 Valkyrie and .308. I think I'm going to work with it some more.
