Pretty good Sir Clayne! Are you using the Burris Signature rings for tilt adjustment? I started using them years ago whilst playing with 22 pistols/2X optics to get to longish ranges [the 2x optics have up to 150 MOA of adjustment range). For shimming purposes the offset inserts are really the only practical option i've seen that doesn't put any stress on the system. I have also found that plastic credit card, aluminum and plastic coke bottles make great shim material that allows me to fine tune the system to take full advantage of the turret if the +/- 20 inserts aren't enough.
I also picked up a Bushnell grid boresighter to set up the system even beofre i go to the range, once i find out where the true zero is along the grid. This really is a great little tool for the long-ranger. It tells me whether the turret is repeatable and consistent as well, and allows me to calculate the shim thickness i need by measuring how much DOWN adjustment i still have left to play with once grid zero is established. I just put a 2X Swift pistol scope on my Ruger Mk III, and have 130 MOA of measured UP in it from 50 yd. zero. That nets me 500 yds. with a 22 pistol. Amazing, huh? The 1st shot out of it after grid zeroing only was a 50-yd. head shot on a prairie dog, and my buddy nailed it. Playing around with this stuff is a kick in the butt for sure!
Shame we don't live closer--would be fun to play with this stuff with someone else as no one around here really gets into the math applications to maximize 1st shot opportunity.
