I am looking for a good general purpose .22 LR/.22 mag rifle to dispatch tree rats. The reds have pushed the grays out and are becoming a pest so I want to decrease the population and have some good eating. Longest shot would be 50-60 yards but most for a time will be more like 50 feet. My .45-70 Sharps is just a little over kill. I do have a .25-20 Marlin that works will but don't want to bang it up keeping it in the truck or on the tractor.
