greg also does another type of bushing on bolts which is what I thought this thread was about. He adds eliptical cams which center the bolt and take up the tolerances as you close the bolt. There are 2 of them on the front and back of the bolt itself. I guess most people call these borden bumps. When you have a barrel done by greg its chambered to a dummy round. you also pick your neck diameter as well. he chambers and throats in 2 processes. I don't know anyone else doing this. everyone else just reams it out to the reamer they have for that chamber and you get what you get. its too bad greg has like a 18 month wait these days.
I personally would still buy a custom action rather than have him do the full truing process. I do have a remington that has the gretan full meal deal done to it, but again custom action would be better still.
