Can a pellet rifle kill a zombie?

no pellet guns can not because they are not powerful to penetrait skin and Zombies tougher to kill then humans and you can not kill a human with a pellet gun

The above answer is incorrect.

Most pellet guns can penetrate the skin, they may not kill you but it will hurt. If you have a .257 or larger PCP Airgun that produces a higher fpe then yes you could kill a Zombie. People need to stop looking at Airguns as toys, they are not toys and the higher caliber airguns can kill. So Please practice Safety!!!

Oh yeah, you need to shoot the Zombie in the head so I would use a 35cal PCP with a 3500psi tank with the valve set to 950psi burst, or a MAC35 with the cartridge set to 4500psi. :-)
