Ya lost me there Obi Wan, why can't you just sight the rifle in for the bullseye at X distance first, then start worrying about wind and varying distances later...
1st ya gotta make sure the rifle is hitting exactly where it's pointed EVERYTIME and you will only do that from a bench and bags or steady rest using tried and true methods...
Maybe quit with the outlaw BS and get serious about learning to sight in and shoot an air rifle... Your outlaw kung fu is weak...
