My long range shooter:
Rem 700 SPS Tactical 308
Millett 6-25 LRS 35mm tube 56mm objective
Originally put this together about a year ago. The Millett scope included a set of rings that seemed to be rather well made. However, they were so tall (1.635") that it was extremely difficult to get a consistent sight picture. The best three shot grouping with the "chin" weld was .551" @ 100yds.
After a considerable amount of research, I found that the original Millett rings were only 1" high. After 20 min on hold at Bushnell (the current owner of Millett), it was confirmed that ring production had been moved to China and there are presently no other rings available from Bushnell.
We did agree that something was lost in translation with regard to how to measure ring height. The Chinese rings had been measured from the bottom of the tube bore instead of the center line.
So the hunt was on for a quality set of rings that didn't cost darn near as much as the scope. Enter Seekins Precision, a small shop where the owner (Glen Seekins) still answers the phone. We determined that their 35mm low (.95") rings should be the solution. Ordered and received in short order. What I hadn't taken into consideration was that these rings are made to fit a picatinny rail not the Weaver that was installed. So another call to Seekins for the matching base.
I now have everything back together and ready for a range trip. While I haven't been able to shoot it yet, the weapon shoulders with a consistent sight picture and "cheek weld" every time.
