I shoot a custom 280AI built from a Rem. 700 action. I shot this gun for 2 years with no problems at all. It shoots great, sub .5 MOA if I do my job. About a year ago I sent my Swaro scope in for service, when it came back I had my smith re-mount it for me..took it to the range and ran out of horizontal adjustment in order to hit center. Turns out the scope mount holes are mis-aligned slightly. The more I have read on this, it doesn't seem to all un-common in the 700 factory actions. Had I known at the time I wouldn't have built on that action though. To get me through this hunting season I used the Leupold windage adjustable mounts and had no problems. Just recently I ordered a new Leupold 30mm scope for the rifle. I have heard some not-so-good reports on the windage adjustable bases, and want to set up this new scope the best way possible given the mis-aligned holes. I know some people really like them though. I have read some good things on the Burris Signature rings that are windage adjustable. What bases would you recommend if I used the Burris rings? Is Burris the best option?? How do they work exactly? Or should I just stick with the Leupold bases? Any feedback is greatly appreciated.
