I got my 54 cal GM barrel that I had rebored to 58 cal today. He said on the phone that he "would get to it when he could" that he was covered up. Turnaround time was 3 weeks and 2 days. I posted about this asking about twist rates etc, on this forum. Advice was to tell him what I wanted to do with it and let him decide, which is what I did. I told him that I wanted a rifle that I could shoot accurately with 70-100gr 2F with PRB mostly at targets, but occasionally for hunting deer. He sent me the barrel back with the following specs: .580 bore. grove depth .011. It is 1:66" twist rate. Shot it today at the range, shot great with .570 ball and .015 patch lubed with TOTW mink oil lube, 80 gr Grafs 2F at 50 yds. My experience with his work is great! Seemed to clean easier too.
