In this video I update the Thompson Center Compass project chambered in 300 Win Mag. We load up ADG Brass with the 220gr Sierra Match King and Reloder 26. We use our Satterlee load development data to choose our loads to test. Federal FED215M primers are used. Groups and velocity data are used to evaluate this combination. We are successful in finding a Low SD group that is less than 1 MOA.
