.22's certainly run the full spectrum, from the Zephyr to this small sized Crickett, as well as everything in between.

Shown is a Crickett brand .22 LR single shot, 3-7x Barska scope. This one is kept in the kitchen for easy access when a mischievous/destructive tree rat is spotted messing around in the backyard. Primarily use the Aguila .22 LR Super Colibre ammunition - 20 gr bullet, no powder, priming compound is the power source, about 550 fps. Adequately accurate out to 60 yards. The 20 gr pellet/bullet works well.
