My girlfriends 12yr old daughter has issues using a normal scope on her CZ 22. So we tried a red dot for her and now wascally wee wabbits are no problem out to about 50-60 metres. Seeing as it worked so well for her, I tried it off the bench at 100 metres, 2 mags full, 10 shots. I was able to shoot a 40mm 10 shot group at 100 no problems at all. The dot covered the target, but only just. They are a great wee optic for spook and shoot with a 22.........or bigger for bigger game.
