I have a 22 caliber spring air pellet rifle. They are accurate and fairly powerful. At 10 meters it will penetrate a 3/4" pine board. Mine will definitely take out a bunny. They are ammo sensitive so try several different brands. Gamo makes one with a silencer and it is legal as it is not a firearm. It takes them about 50-100 rounds to get quiet when they are new. The higher velocity in the 177 are harder to silence. There are some expensive ones that you pump up which are very quiet and will give multiple shots on a charge. Add some snares or mouse/rat traps to that kit.
