Aguila Ammunition Super Colibri .22 20-Grain Rimfire Ammunition

Yup, turns your 22 into a pellet gun basically. No powder just powered by the priming mixture.

The will not come near to cycling a semi-auto but a single shot, bolt action, some pumps and leaver actions they function well from. the short barrels of handguns will give more velocity than rifles with these loads.

I have had to push a few of the bullets out of the barrel on rifles with a cleaning rod.

When they first came out I know several that used them on pests around the house out of a handgun and they said they worked,

I shoot squirrels out of the garden with them. Both my .22’s auto’s shoot shorts, although they don’t eject by themselves, it’s like shooting a bolt action. Super quiet, less than any pellet gun I own.

When I was a kid,(70) some years ago, we had B-B caps. .22 short with just the primer and a B-B pushed in the end. Worked good on birds.

Yes, and they are unbelievably quiet. My cat can fart louder than these. lol

Same. Quieter than my pellet rifles and have killed a pile of squirrels with them.

Love them. Quieter than a pellet gun when shot out of a rifle.

Perfect in my Old Model Single Six. They also make a short brass, LR length 50 grain lead bullet cartridge that's really good for shorter range small varmint control.
