Every Airgun is unique and every different pellet choice presents its own ballistic challenges.
Although I only punch paper for setting up my Airguns; this method of finding your optimal zero can easily apply to everyone.
BUT
it is a lot of work, albeit satisfying work, which results in a great visual tool and very useful information about your Airgun and your pellet choice Ballistics.
For starters you can zero your Airgun at 25 yards - I chose 30 yards - but I could have chosen 25 or 35 yard. At this point I’m just interested in finding the apex of my trajectory.
Next step: using some 8”x11” graph paper, tape them together on some coroplast; then draw a straight line all the way across the top and then mark your line with a X every inch or so.
Label your X marks by the 1/2 yard from 10-55 or however far away you plan on shooting.
i recommend the next step to be done from a bench to minimize variables.
place your target at 10 yards and begin shooting With your point of aim on the line at the X for each distance. Your pellets point of impact maybe or will be lower than your point of aim, and that’s part of the important data.
Below picture shows my results shooting .177 jsb 13.4 RD’s from a Redwolf at 812 fps.
when finished you will have created a real life ballistic chart for your gun and pellet choice. Useful for determining holdovers and or clicking the turret!
Of great interest to me was how quickly the pellet began dropping after my chosen zero of 30 yards. 3" drop by the time we reached 55 yards.
wind was actually blowing left to right in accordance with the pellet drifting
