Gentlemen: I've got the bug to reline a .22 barrel, any and all advice is welcome.
I've got a friend that has a small tool grinding business that is willing to grind a drill for me, adding on a pilot.
Question is what dia. should the pilot be?
Thanks:

I'd give Brownell's a call. They sell the liners, drills etc. They can advise you on what drill size is needed for a given brand of liner. 800-741-0015 or http://www.brownells.com

The pilot diameter on the .22 liner drills Brownells carries is .216" X 1". You can also rent the liner drills, take a look at http://4-dproducts.com/index.html

The largest problem with drilling out the barrel for the liner is binding the drill and breaking it off. Go slowly, don't turning backwards, clean the chips out of the flutes and the bore often. That last may be the most important of all. Lube the cutting tool and be certain all chips are removed from the bore when a cleaning is done.
