On a No. 1 B there are very few variable scopes that will set far enough back that you don't have to crawl the stock as the eye relief diminishes on higher power. I have tried both methods noted, the extended rings and the Weaver base that lets you set back. I put a 3-9x40 on mine and used Burris extended rings. It helped some but if I am wearing a heavy coat it is still not perfect. I finally just went with a 6x Leupold and it worked pretty well. I used it for coyotes and Whitetail.

95 gr. SST's for deer and coyotes with 4350 were great.
