Really appreicate posting those drop chart numbers. 1)makes a fella envious and to I like to mess w/numbers. Hmmmm, lets compare drop charts[img]/ubbthreads/images/graemlins/confused.gif[/img] Range Kirby's Roys 445 -0.7 -1.1 522 -1.1 -1.8 567 -1.4 -2.3 612 -1.7 -2.6 Ran a curve fit on your numbers and figured that you truncated instead of rounded up. Using my curve fit numbers and rounding up your 522 would be 1.2. 567 would be 1.5 and 612 would be 1.8. I think that it is amazing that you could, from shooting calculate that 0.1 Mil adjustment.
