[QUOTE="Mikecr, post: 509027, member: 1521"] 10moa @ 50yds = 1.047198 x 10 / 2 = 5.236" A 10% error would be 0.5236" +/- 10% of 5.236 would be 4.71" and 5.76" You can set your adjustments true doing this: [url=http://www.longrangehunting.com/articles/reticle-perpendicularity.php]Reticle Perpendicularity[/url] Make sure to use a ScopeLevel. I'd dial up/down the BDC at laser ranged targets to confirm it's accuracy. Afterall, whomever is building your BDC should be taking care of the ballistics of it all for you. That's what you're paying for. Or this: [url=http://www.arcanamavens.com/LBSFiles/Shooting/Downloads/ScopeChecking/]How to Optically Check a Rifle Scope[/url] Personally, I use electronics and dial in the field. I account for the 'extra' stuff like slope angle, coriolis, and spin drift. But then the kill zone on groundhogs is relatively small, and I give myself only 1sht on any particular GH per day(my rule). I think you'll do well with your plan. [/QUOTE]
