With the high prices and spotty availability of rimfire ammo, I too have gotten back into air guns. Mine run the gamut, from the Red Ryder I got years ago for backyard 'cat scat' duty (not powerful enough to harm the ferals) to realistic BB pistols (M1911, Luger and Mauser C96), to various hand pump and break-barrel springer rifles, and a few CO2 Crosmans.
My Stoeger X50 in .177, and Benjamin Trail Nitro 1100XL in .22 are my favorite rifles. The CO2 Crosman 2400T carbine in .22 is very accurate too.
Being single, I do shoot inside the house, using a good pellet trap.
I stocked up on what should be a lifetime supply of pellets and CO2 cartridges, so I can still shoot if powder-burner ammo goes away (never know with the current misadministration). I do handload and keep a goodly stock of components for centerfire, but no such luck with rimfire. I have a couple thousand rounds of various makes of .22LR and .22WMR, but I guard it and shoot only occasionally. The pellet guns allow me to shoot much more often. Having a nearby hunting lease means no problems with inner-city shooting or risking the idiots at the local public range (no RO).
So for now, I am satisfied.
