Barrel Wall Thickness

[Bruce Day]

Jack, here's my take on it. I know others have studied the issue also, and I am a big fan of the Bill Murphy philosophy of "don't mess with them".

1. No, except that unpitted bores are easier to clean. So just scrub more.

2. No

3. Don't think so. Would you rather have a small single isolated potentially weak spot or would you rather have the entire barrel length potentially weak?

4. Don't know, other than a full length liner, which is a drastic and expensive remedy.

"Is there a means to fill a pit?"

I've discussed with a few TIG specialists, and no.
