In this video I update the Thompson Center Compass project chambered in 300 Win Mag. This was a $200 rifle that we are going to test to see how accurate it can be with a very budget setup. In this video we go over more reloads in our Thompson Center Compass and updates moving forward. We load up ADG Brass with the 220 Nosler Custom Competition and Hogdgon H1000. Federal FED215M primers are used. We use the Satterlee load development style to evaluate this combo and find a velocity Node to use for our next time with this powder.
