New air rifles have excess oil in them and will be loud until the oil is shot out. Some air rifles are equipped with supressors and they are legal and do work as long as the velocity is subsonic meaning use lead pellets not PBA. The air rifles can be deadly on pests.
I have used the CB caps in my garage for target shooting and getting a 22 on paper. I have had no complaints so far. I have a good bullet trap. They are louder in a pistol though. There is a really nice suppressed Ruger 10/22 over at the gun shop $$$$.

I don't think you need worry about the ammo, just poke them with the barrel.
(Overall length is 42.6).

I remember this one time at band camp,
I saw someone fasten a used water bottle onto a gun & cut the end off & stuffed the bottle with a sponge. Unfortunately anyone (unlicensed) trying anything that causes a gun to become quieter in this manner can receive a 10yr ride in jail & a magical $250,000 fine

I got a brick of Hummingbirds a year or so ago.

I love it. It wont eject from a semi auto so I only use it in the bolt actions.
Not speaking from experience here (because I believe that the governments rules on silencers are ultra-respectable), but from what I've been told, if you cut about a one inch circle out of the base of a 20 oz. plastic soda bottle, add no foam to the inside of the bottle; just keep it empty, and wrap enough electrical tape over the end of the barrel that the bottle will push on and hold solid... it's so quiet that you can hear the firing pin hit clearly.
It's not the strongest ammo by a long shot but will kills squirrels and rabbits at 35 yards with a head shot.

I just received the Colibri Agulia 20 grain 22 l.r. ammo today and put 5 rounds into the magzine. It won't be pushed in the receiver by the bolt since the bullet is much shorter than the 22 l.r. I'll have to manual feed it. As a result, I won't be able to use the magzine the way it should be. Instead, I can still put 5 rounds into the mag. and after each shot, manually feed the next round. The cartriage will eject without any problems.

I'll go the range tomorrow to test shot the ammo with my CZ 452.

Thanks.

I use the Colibri's all the time "silent" pest control out of my Winchester 290 and they work very well. My only warning is that occasionally one will get stuck in the barrel and if you shoot again you will get a mess stuck down your barrel. I had a guy at the gun store tell me about someone who had 8 bullets stuck in his barrel before he noticed nothing was going thru! If you have a dud you can generally hear it as a dull thud.
That is the only problem with them, they are deadly silent for small pests. I wouldn't try shooting anything much bigger than a squirrel or a rabbit though as they really don't have that much weight or velocity.

I shot 5 rounds with my CZ 452 today. None of the bullets hit the target, which is 25 yards away. Two out of 5 bullets got stuck inside the barrel. I used boresnake to clear the barrel everytime I made a shot.

I just didn't work on my CZ 452. Now I'm stuck with 500 rounds of Colibri ammo. Is there any remedy to it? Could I sand the bullet to make it a bit smaller in diameter so that it'll exit the barrel. Or, it's just the primer that is not powerful enough to propel the bullet out of my 24.6 inch barrel. BTW, as I mentioned CZ has a tighter barrel than typical American 22 l.r. barrels.

Can someone help? Thanks.

Get some Super Colibris. The Colibris are designed for handguns, I believe, but I've shot 3 or 4 bricks through rifles with no problem. The Super Colibris are faster.

BF- find someone that has a bolt action AMERICAN rifle, and do some horse trading with those 500 rounds. You have a long tight barrel, and the primer only propulsion system runs out of steam before it runs out of barrel. Did you read on the Colibri box the part about not using them in rifles?

Thanks all for your suggestions.

I do intend to get a 22 caliber handgun - a Ruger MKIII with 5.5" barrel in a few months and wonder if anyone has ever shot the Colibri with the Ruger. Maybe I can use these ammo with my pistol.
