New England Custom Gun (bestguns@comcast.net) fitted rings to the claw mount bases on my Greifelt drilling with a turnaround time of about six weeks. The drilling (16/65-16/65-7X57R) turned in MOA groups with my handloads yesterday, using the Vari-X III 1.5-5X Leupold I had mounted on it. I can hardly wait 'til deer season opens (November 11).
