In this video I update the Thompson Center Compass project chambered in 300 Win Mag. In this video we are exploring if we move our projectile closer to the lands we get better groups. This was a $200 rifle that we are going to test to see how accurate it can be with a very budget setup. The brass we use today has been fully prepped including Neck turning. We also look at the case and bullet run out to evaluate our reloading process.
