Not everyone lives in Wussie Jersey like we do. The OP may live somewhere that people actually mind their own business and aren't afraid of their shadow.
OP, .22 Super Colibris don't over penetrate, have a lot more thump than an air rifle, and are quieter to boot.
My immediate neighbors on both sides are no problem and in fact encourage me to shoot squirrels, however I am sure there are some around here that would freak out and call the Paramilitary.
Ummm I have to disagree on the .22 Colibris at least Vs my Feinwerkbau 124D air rifle of which is dead silent if you are standing more than about 15 yards away the only thing that can be heard is simply the pellet zzzzziiippppp by you and thump where it hits.
Plus my FWB 124 I can put 10 shots under a dime at 50 yards and put 15 shots in 1 1/2" at 100 yards.
and BTW my air rifle has MORE power at about 13+FPE whereas the Colibris are only 11FPE and not as accurate.
Back in the 80s the grandfather of one of my best friends had an Avocado farm around Hemet California, was well over 1000 acres.
For a couple of years we went there for Thanksgiving and I shot 2 Wild Turkeys both around 18-20# with my air rifle, same one I still own today.
Both about 40 yards away, both dropped in their tracks with a head shot.
All the hunting that I have done in 35 years has been with my air rifle, Rabbits, Dove, Quail, Grouse pesting squirrels and one rabid Raccoon.
I use Predator pellets so over penetration isn't really a problem
