Thanks, the GHE is a fine gun and fits me well. When I miss, it's just my fault.

I think when honing a cylinder, the depth of cut (reduction in BWT) would be .0015" of metal around the inside circumference to achieve .003" increase of inside diameter from .729 to .732

Never done it, but that makes sense to me. I stand to be corrected by the experienced.

Cheers,
Jack

Jack, indeed you are correct I'd think. In either case it suggests that the gross amount of eccentricity I found in the returned DHE was the result of work done in Meriden originally.
