Probably about 98% of the bunnie-hunters here use 22lr exclusively, the ones who don't normally use a .410 with light shot. The tree-rats here are too small to even worry with... I use an ATI GSG-5 with Aguila SuperMax Hyper Velocity 30gr on bunnies and Aguila Interceptor 40gr on fox. The Interceptors will take out a fox at about 80-90yd, but after that, it's not much good... Looking at getting a .204 or .223 for the long-range fox shots.
