I have a .22 cal Gamo Whisper.
After getting the scope mount tightened and locked in, it's a tack driver. The .22 are quieter than the .177 due to lower velocity. My neighbors can't hear me shoot - at least it's not over the Doug Co db limit.
Have taken P-dogs out to 150+ meters. Agree on the poll, but there's no critters to be found. .22cal hollow points take them out quick. Except for the one P-dog I hit in the foot at around 180. LOL
I have a range card in the upstairs bathroom window. LOL. Wife thinks I'm nuts. Strelok app has air rifle ballistics if you're so inclined.
