Response to scope mounting problem
Burris makes a specialized set of rings to correct the problem of turret "run-out".
Using oblong plastic inserts, you can add up to 40 MOA at 100 yards to any POI axis.
0,+5, +10, +20, -5, -10, -20 inserts positioned within the rings achieve the same as shimming, while maintaining 100% contact between the scope tube and the rings.
Since you're talking springer, I'd say they'd work perfectly since they hold like a vice while still not marring or crushing the tube.
Check them out, they're worth the money in my opinion.
