https://www.airgunnation.com/topic/doc-stanley-his-dial-of-death-accuracy-graphic/ all that you need is contained here. I did the same and went to www.scope-weeks.com and bought the necessary products, he has a cap for your desired scope (SWFA) elevation turret that you can make a tape for. I then used Strelock Pro, the spreadsheet icon on bottom of iPhone screen first row far right; used the data in the “vertical correction column” to input the yardage’s and corresponding elevation turret clicks into the scope-works program that comes free when you buy a turret cap from him. Cost me $55 plus shipping, but was very easy.
I have this set up for my Taipan Vet 22 short on SWFA 3-15 FFP scope.
