I usually work on my own stuff but when it gets real technical, I turn to Jim See of Center Shot. He recently broke down my Barrett for a accuracy upgrade check and cut, threaded and re-crowned the barrel for my suppresser when my stamp shows up soon. I also picked up one of his muzzle breaks for the Barrett for when I’m not using the can, there’s a big difference in the new break versus the Barrett factory when shooting the 338 Lapua Mag.
He’s doing a 260 build for my son this winter, His work is unreal when it comes to accuracy in either F class or tactical events. I have been drooling over some of his long range tactical / hunting builds as well.
