I dont click any of mine (ANY CHINESE SCOPES) and just holdover and click with only my Japanese and European scopes. I don't even use computer generated ballistic programs and just put targets from 10 yards to 125 yards in 5 to 10 yard increments to get actual real life ballistics shooting at the actual targets the old fashioned way and take lots of notes and put stickers on my Japanese and European scopes.
Then you can know the real life first hand shooting drop levels and distances and testing trajectories and you won't need any shraylock or chairgun ever and you be all natural greatness! Grab any gun you will know where the pellet should hit you do this enough even at 100 yards. I can make accurate guesses minute of bird just by the weight and speed of the muzzle without any programs.
