First off, just know that I'm not too lazy to do the load development. I've had this 8# of TAC for almost 8 years, and tried it in .308, multiple bullet weights. Also in .223, and 6.5 Grendel. Tac was edged out, accuracy wise, in all my phases of testing, so before I condemn it to load blasting ammo with mixed head stamp brass and the worst quality pulled bullets I ever got suckered into buying, I thought I would ask around to see if anyone has a go-to, or a pet load using TAC, any caliber.
