Thompson Center Compass – 300 Win Mag – Sierra 220 SMK with Vihtavuori N560 Velocity and Pressure

In this video I update the Thompson Center Compass project chambered in 300 Win Mag. We load up Winchester Brass with the 220 gr SMK with Vihtavuori N560. We use our Satterlee load development style to develop our velocity curve. Federal FED215M primers are used. Velocity data is used to evaluate this combination for future use.
