I set up a Birchwood Casey rimfire dueling tree in my back yard. This because I get bored shooting paper at the local firearms ranges and much prefer shooting steel. So I bought a Vevor pcp air compressor, Hatsan Jet 2 .22, and the dueling tree, to scratch that itch in my back yard. I am shooting off hand at 3" plates 15 yards distance. The Jet 2 is plenty accurate for 3" plates at that distance but it doesn't hit hard enough to reliably swing the plates around, even after applying lithium lube to the dueling tree. Ergo the question. How many foot lbs do I need. Maybe the Jet 2 in .25 would have gotten it done, but having shot the .22 for a couple months, I don't love the feel of the gun, + I am wrong handed for the lever, so still a lower level of satisfaction than I would like. Reading, I am not finding a specific answer anywhere to my main question. I suspect that a HW 44 in .22 might be a good choice for its accuracy and power, and the ability to switch the lever to the wrong hand, but I would like to read the opinion of the experienced folk on this forum. Also, in the $1K range of the HW 44 there might be far better choices of which I am unaware. Also looking at the .25 Viper and any GK1. For myself the only issues I have with the GK1 are, it's more of a hand cannon than a pistol, and my Vevor only pushes to 4500 PSI.
