I attempted to work the caculations to figure out the CQ reticle conversions for myBurris MTAC 1-4X myself only confused myself further. Here is the ballistic data from JBM:

The Burris CQ reticle corrections (MOA) are:
Center Dot- 100 yd zero no correction
Dot #2- -3.3
Dot #3- -6.1
Dot #4- -9.6
Dot #5- -13.6
Can one of you pros who are much better at math calculate the yardages of the CQ dots for my .300 balckout data above? (and perhaps post the formula for doing so, in case I will be able to comprehend it....)
I hate to ask, balancing a checkbook is about the extent of my math capability. God gave me height and good hands, not and abundance of math talent...
So, I therefore humble myself to you guys smarter than myself. Feel free to bust my balls if you like, we cant all be math gurus.

PS- FYI, the little AAC/Remington Model Seven .300 BLK averages .71" at 100 yds with the Remington Premier Match 125gr OTM at 4X from a bipod, just in case you were curious what I was using.
Thanks gents.
