Shooting my 22 handguns with their shorter barrels with the above ammo is noticeably louder, though. Yup, 22 handguns with Quiets or even CBs are louder than I like, so I just reserve my 22 handgun shooting for trips to the club range. Not shooting my 22 revolvers is bad enough, but even my beloved Contender 22 LR rigs are louder than I like with CCI Quiet.

Many years ago, I remembered shooting some of my 22 LR handguns with Aguila Colibri, but that ammo hasn't been available for many years. Recently, though, I found some more, so thought I would give it another try. The Colibri is 22 LR with a 29 grain bullet and the velocity is rated at a measly 420 fps, compared to the rated 710 fps for CCI Quiet or CB Shorts.
How loud could it be?
Shooting the Colibri in my S&W Model 63 with a 2" barrel, I still get a noticeable "crack". My 6" revolvers with Colibri are quieter, but nowhere near as quiet as shooting Colibri in my Contender. In my 8 3/4" Contender 22 LR barrel, I can actually hear the bullet hitting the soft dirt in my back stop. I have air pistols that are louder than that.
What about accuracy? Shooting from my deck puts me at 26 yards from the target. At that distance, the hard truth is that even in my Contender, the accuracy of the Colibri is "miserable". Total waste of ammo. If you shoot Colibri in a 22 revolver at this distance, you better have a really large backstop. Not kidding, here.
Not ready to give up, today I went down in the yard and set up at a lasered 15 yard distance. Shooting from a lawn chair with one elbow braced on the arm of the chair, much, much better. After a rough adjustment of the excellent open sights, I started shooting this 2" bull and did some more tweaking of the sights. Still a long way from what a Contender can do with premium ammo, but good enough to let me shoot my Contender at home, so I am very pleased.
