Thanks a lot for all the info guys! I finally found a load that the Grendel likes. I shot 5 waited 10min, and used a chamber chiller. My goal was to keep the barrel cool enough to hold it. Seemed to really kept an even barrel temp. Not sure how much that mattered, but finally I’m seeing potential out of this BCA upper!
