Just had two of my shotguns (Nova and Remington 20 gauges) drilled and tapped utilizing the Sumtoy Mount coupled with my Burris FF3. Took them to the range yesterday to get them sighted in and I don't have enough adjustment on either to hunt with. Both shoot low utilizing all my adjustments on the FF3. About 6" low at 40 yards. Any ideas folks?
PS. Drilling and taping was done by a gunsmith who builds 1000 yard benchrest rifles. He knows what he is doing for sure and charges accordingly.
Double PS. I had one of the Burris FF3 on my Nova using a weaver base and the factory Burris mount, but decided it was too high and thus went the Sumtoy base route. It did not shoot low with the Weaver base as I had enough adjustment to center the pattern.
