How much does a pellet gun that can kill a squirrel cost?

If it's a pellet gun them most pellet guns are capable of killing a squirrel. Check the FPS (Feet per Second) and if it's over 400 FPS that should be sufficient. Expect to pay $60 and up for a pellet gun. Crosman makes an Excellent pellet gun that is rated at 610 FPS Called the American Classic and it cost $70. I also suggest using Hunting (Hollow point pellets) these will be the most effective.
