Kent, please excuse my ignorance with the following questions but I do not understand the significance of the information you are asking for and just what to understand. 1st - Aren't all liners supplied by supply houses like Brownell/other and then gunsmiths just bore and install what diameters are commonly available? 2nd - If not then I may understand a little better then - if this man makes his own liners - Does he?
If in fact, he makes his own liners at whatever diameter; number of grooves/depths; and twist rate as customers desire, then I fully understand your interest to see the cutting and polishing of his finished product as installed.
Or -- Are there other factors that I would be interested in looking at if having a barrel lined? Like bends or curves or waves or off-center boring in the final install?
I have heard this man's name mentioned on other forums lately but have not search out to see if he has a website. People just supplied his phone number to the questioning parties.
As reference, I had one rifle relined back in '93 and I sent it off to someone that was suggest by a friend and it came back great. But that was a long time ago and I did not know to ask questions?
Thanks for the helpful hints, you could provide.
