Quiet .22's

In a thread in the rifle section I asked for advice about pellet rifles for some incognito use. Member nitechampion gave the advice to use quiet .22 ammo. Thought this was a good idea so procured three offerings from CCI locally.
Rifle was a 1930's Winchester model 60a target model with a 27" barrel, rear lyman peep and lyman front globe site.
Shot handheld off bench, 10 shot groups, 25 yds, with Pact1 chrono placed 10' from muzzle. Limitation was my mid 60's eyes with bifocals.

CCI CB short. Factory specs 29 grs. 710 fps, 32 ft-lbs energy.
My average was 652.1 fps. with a spread of 57 fps. Mr. Ackley's formula computes to 27.3 ft-lbs energy.
Report very soft with a couple noticeably quieter, probably the one's on the slow end of the spread. Case is short rifle.

CCI CB long. Factory specs 29 grs. 710 fps, 32 ft-lbs energy.
My average 658.1 fps, spread 99.5 fps, 27.8 ft-lbs energy.
Case is long rifle. Report seemed even.

CCI quiet. factory spec 40 grs. 710 fps, 45 ft-lbs energy.
My average 606.9 fps. spread 253 fps, 32.7 ft-lbs energy.
Case is long rifle. Upon examining chrono results I found one shot in this group 150 fps. slower that I believe was an error throwing off report.
Edit: All were quiet enough for my use. Was surprised the 40 gr. offering was as quiet as the 29 gr. All seemed about equal.

Next step will be usage in real world to check performance. Vermin here I come.

Been using CCI quiet for awhile now when shooting with my kids. It’s pretty accurate out of their bolt guns and extremely quiet compared to other sub sonic .22lr offerings on the market some of which I don’t believe are truly subsonic. It’s definitely squirrel accurate for me and it’s affordable. Unfortunately I’m having a hard time finding it locally the last few months.

I've been using CCI and Remington .22Shorts forever for backyard pest control and the occasional small pet euthanasia. ...no awaken neighbors, nor cops showing up at my door. I keep a box of Shorts on my desk in front of me, and my Iver Johnson 55A loaded with them at all times not far away.

I still prefer them for squirrel hunting too, especially in "squirrel towns". Less likely to spook the others.

Does anyone have any experience shooting CCI quiet out of a 22 pocket pistol in terms of sound reduction?

They won't cycle any standard .22lr semi automatic pistol or rifle from my experience.

Thanks. I'll stick with louder stuff then.

I'll have to try them again to be positive, but I'm pretty sure they cycled in my S&W Victory. But if not, just run it as a bolt action pistol. Without a bolt.

Update: I was mistaken. The quiets won't cycle the Victory, but the SV CCI will. I must have been shooting the quiets in my bolt action Marlin 25.
