In this video we use the Tubb Final Finish system on our Thompson center compass in 300 Winchester magnum. I cover loading this system. We shoot Federal Gold Medal Match before and after the process is complete to see if our groups improve with this system. We run a bore scope through the barrel between compounds to see the changes as we go through the process. The also compare the distance to the lands with several projectiles before and after to see the changes to our rifle moving forward.
