Here’s my groups from this morning shooting from my living room (70 degrees inside, -30 outside)at a target outside at 25 yds:
Air density difference between inside and outside may have had some effect on the called flyers (?), but I’ve experienced the flyers before with this ammo.
Here's another hypothesis. Those little low-power Quiet rounds got all warm and toasty in your cabin, then when kicked outside into that -30F at 710 fps, they acted like pets and said, "Hell no! We're not going out there," and tried to get back inside again. Hence the less than stellar groups.
I've been on a subsonic kick for the last few months. For the last few years in my 10/22, I've used mostly Mini-mags and even some Velocitors. But those were the days before I got serious with sights; I was mostly using Tech Sights back then, and happy to get 1.5" at 25.
But since my eyes insisted that I get serious and add better sights -- first a red dot, then a progression of a couple of scopes to my current Vortex Crossfire II 2-7x32, I've been playing around now (until winter closed the ATV trail to my shooting area*) with quasi-precision shooting. (* I've got 50 wooded acres out my apartment windows, and even got some targets set up at 25, 45 and 60 yards for sighting practice during winter, but my neighbors would call the cops if I did any target shooting from there.

)
I've been working (and will continue in spring after ice out and mud season) with CCI SV, Subsonics, and Quiet Semi-Auto (SAQ in my notes; 835 fps). I also have a couple of boxes of Aguila Subsonics to try out; haven't yet at all.
I also bought some CCI Quiets, but mostly tried them in a Mark IV 22/45 (that I named Dredth, vs Dearth which is my 10/22 project; the 22/45 is on the way out of my collection now -- I've realized I'm just a rifle guy when it comes to .22LR).
I haven't yet tried Quiets in the 10/22, but plan to. So this is interesting reading, and the results are about what I would have expected in terms of shorter range accuracy and big drop after 50.
Nothing much to report yet from the 10/22 (winter hit before I got a chance to try out the Vortex).
But I can say that the 22/45
MUCH preferred the SAQ. I mean by a long ways. These are 3" stick on targets on cardboard. These are all 9 shot groups at 10 and 15 yards using a Swampfox Kingslayer reflex red dot, and using a rest. The holes circled with blue sharpie are just the peg holes for holding the targets.
I know I tried the plain Quiets in the pistol, but for some reason, I didn't keep the target results. I think I decided it was just too much trouble racking the pistol after every shot, so bumped up to SAQ. I'll still try the Quiets in my 10/22 next season.
