I'd like to show you guys who are running 34mm scopes what I consider to be the absolute best unitized rings I have ever used. The mount is made by Near Mfg., and it will fit my S&B 5-25x56 AND my Premier Reticles 5-25x56. I suspect it would do as well on the PR 3-15x50. I had my Schmidt and Bender in the mount and shot over one hundred Weatherby 30-378 Improved rounds. When I pulled the S&B out I expected to find some light ring shadows. There weren't any! I bedded my Near picatinney rail onto the action to insure a stress-free rail, and then clamped the mount on to the rail and went through a 50 round barrel break in, then another 60 rounds (over the course of a 3 day weekend) fireformed. Near Mfg. has the best mounting system for big scopes mounted on long range boomers - I have no doubt at all.
