I moved from powder burners over 10 years ago. It's still a learning experience. Nice part for me, if I want to tun a gun, I can do it at the range. No need to load 5 rounds of one type, 5 of another, find a day to go to the range, take records, and such. These aren't my strong point. However, with the guns that have adjustments on the gun, you can tune at the range.
Best part though, when I go to the range there aren't many air rifles, so everyone has questions. Last time, at 75 yards, I let one of the range masters shoot. First shot ever from an air rifle, hits the bullseye. I mean, dead center. Nice to give others a good experience on their first shot.
And as I age, recoil is a major problem. Between age and Muscular Dystrophy, airguns allow me to keep shooting.
Enjoy the dark side. You never stop learning and the fun never stops either. Always a challenge.
