Brad Christiansen –
I just finished load development in my new 6×6.8 coyote upper with the barrel cut to 16”. 31.3gr of XBR8208, 58gr V-Max, Starline brass to a COAL of 2.216” gave me 3283fps, SD of 7.3, an ES of 21fps, and a 3 shot group size of 0.226”. Another 0.010” off the lands and it reproduced (0.251”). I didn’t think that sort of accuracy was possible out of an AR. To say I’m impressed is an understatement!
**DISCLAIMER- there is primer flattening and mild pressure signs in my gun. Always start low and work up slowly**
