Chad thanks for that info that is a great tip!

I do have another question though I will be setting my barrel up through the head stock with an outboard spider and 4 bolt spider fixture on the front.

I will dial my barrel in with a range rod as best i can with the .0001 indicator.

NOW what if i have runout on the out board side of the barrel lets say as much as .030" on the muzzle end.

Usually you want to clock the barrel to the 12Oclock position to have your bore point up.

How do you index both the bore and the flutes as to line up the bore pointing up and the flutes strait up and down?
