FreQRiDeR Posted September 15, 2017 Report Share Posted September 15, 2017 I've been playing with Excel Ballistic calculators and started writing my own for kicks. I made this BDC Calc to recalculate published scope subtentions at 9x/100 yards to various magnifications. You can then use the table on the bottom to calculate range from the various subtentions. I have Excel on my Smart-ass phone so I can run it in the field and range with the BDC reticle. BDC SUBTENTION CALC.xlsx Quote Link to comment Share on other sites More sharing options...

FreQRiDeR Posted September 17, 2017 Author Report Share Posted September 17, 2017 Updated moa to equal 95.5 inch instead of rounded to 1" (more accurate) and zoom/subtentions formula improvements. BDC SUBTENTION CALC2.xlsx Quote Link to comment Share on other sites More sharing options...

BDC SUBTENTION CALC2.xlsx Disregard this last version! I got confused. Subtentions on this scope are in inches already so no need to multiply by moa! Sorry Admins, can you delete this last post?

FreQRiDeR Posted September 27, 2017 Author Report Share Posted September 27, 2017 I have updated the Bdc Calc to have upper and lower subtentions, better directions, nicer reticle diagram and the sheet is now protected so you can't inadvertently modify things. I have also added my MOA CALC as well. Let me know if you find any of these tools useful. Enjoy!
