I believe they are okay in some areas for class C (pests). Don't have the regs handy. Even so, I suggest >> 500 fps or .22lr. My experience was that even a .22 at just under 500 fps was iffy on big squirrels. Before sub-500 airguns were banned (by-law) within city limits here in lotus land, I had a squirrel problem and used the 2240 to good effect for a while. Then I had a close-range centre-chest hit on a robust squirrel that just turned around and yelled at me, ran off, and came back a few days later and took revenge. He even sprung the rat traps and dragged the traps off and hid them. It was an unusual experience...maybe he was wearing armor.
Maybe I shouldn't have sold the SKS?
