Griz,

I use Dave Norin for this type of work. He has put several guns back on face for me. Here is his website:

This is a quote from one job he did for me:
Quote:
The job came out fine. I was able to move the barrels back a full .005" and smoking the barrel breech brought it to full face contact. The dolls head and underlugs were a bit trouble some but it opens and closes just fine. I also half-soled the bolt for full lock up, ie the barrel beech is on the face and the lockinglugs have full purchase and downward holding power
