Thanks for the info, Randominator. I guess I'm just lucky. I have stacks of targets from 50 and 100 yards showing 3 and 5-shot groups averaging 1.5 MOA with the Lee bullet, pretty dang undersized on all but the base band, from 7, 8, and 10" ROT barrels, including a 10.5" AR, two 16" ARs and a .308 Winchester bolt-action, all suppressed, and using powders ranging from Titegroup to Reloder 7. Do I get yawing? You betcha, sometimes. But they group for me. I've been trying to figure out for a long time why so many other people have trouble and a few don't, there has to be something to learn from it.
