FFS .. think about what youve just typed GPM......
your last 3 lines.....
now go and play with your programme and change velocity by 100fps...and range by 50 yards....you are guessing after all.
the WHOLE POINT of the old rule of 3...3" high at hundred yards was to allow point n shoot out to 300ish yards without fluffing around...and you DONT NEED EXACT numbers for it to work....
I would argue BY ALL MEANS print up a drop chart off the computer but validate on paper to confirm
of just sight rifle in and have rough idea of what drop you are going to have at your roughly guessed range...below 200 yards unless you using something really slow its not going to matter.
