I have this
pellet gun, my son left it when he moved out.
I also use the Crosman Destroyer pellets with it, anywhere in my back yard is lethal for the bushy tailed tree rats, it will put a pellet right through them.
A family of them had chewed through the fascia of my house and setup above the guest bedroom... I waited for them to come out of the hole and popped them, one at a time.
The goal is to make them an endangered species
