I’ve got a UMAREX that I picked up cheap with 24X scope and a pile of 10 round magazines. The guy I bought it from tuned it, and he’s currently the spring air rifle world champion. I believe those also come in .22 and .25, mine’s .177 (which would still take a coyote if you got him in the noggin sweet spot)…
If I ever catch a Coyote inside my fence the Coyote rollers will be going up. They could easily kill my little 25-pound dogs but could never get one over the fence. My three big dogs outside kept them run off but all three are gone now from old age. Since the last one passed two months ago, I have been more diligent about watching. They will start coming closer to the house with the big hounds gone.
