I am trying to dial in a barrel that is supported at the muzzle by a spider in the headstock and the breach sticking out of a 4 jaw chuck. I have rounded brass pivot points on the 4 jaws to allow the barrel to pivot without bending the barrel. I started with centering both ends to as close to zero as I could. I then started to measure two points inside the bore and of course found they were out by .0005. So starts the process of moving back and forth between adjustments at the muzzle's spider and the breach with the 4 jaw.
Anyone have a strategy to share for how to move back and forth with these two adjustments? I'm driving myself crazy tweaking one end and then the other to find the other point of measurement is now out by .0005.
One more question. How much barrel stub to you have sticking out of the chuck? I'm thinking the less the better, right?
