GGT is exclusively a training organization. But occasionally, we learn of an advance that is so remarkable, we just gotta talk about it. The patented StraightJacket barrel system from TTI in South Carolina is the most impressive advance in shooting I have ever experienced. My buddy, Del, had a 300 Magnum rifle done because he could not get it to shoot well. He is an accomplished reloader, and in spite of his best efforts, the groups never impressed. After the StraightJacket, they shrunk literally 60%. And, the considerable recoil was tamed to the level of a .308. VERY IMPRESSIVE.
