I got into airguns heavy in 1980 when I was 10. First were the 760's, then a 1322 and a 2200. Plugging bleed valves was a hobby, and 50 pumps later getting a BB through one side of a 30 cal ammo can in my bedroom. Many rabbits, squirrels, gophers, rats, skunks and other critters fell to various .22 cal pellets.
About 15 years ago, I got bit by the bug again and started collecting a bunch, and doing mods for accuracy and such. Some of the ones I have that I recall from my youth, that my friends Dad had. I've got two .22 cal 38 T's, a lefty Mk1 .22 cal as well as some current 2240's, 357's, 1322's and such. But by far the coolest, are a pair of the 1968-70 1100 CO2 shotguns. When I bought them about 10 years ago, I found a guy in ND that was reproducing the shells for them and I bought a few thousand of those. I used to walk around my property and flip strategically laid out pieces of wood and tin, and go to town on the mice. I've got 8 cats now, and they do a great job of keeping them in check now.
