The .22 caliber rimfire is a rifle and pistol round. They are ideal for destroying paper targets, vermin, flies in your house, annoying party balloons, and zombies. This is all at a low cost to the consumer, as .22 rimfire cost 25 cents per box of 100. That is a lot of dead (or re-dead) zombies. Since the .22 has almost negligible recoil, well placed shots are pretty much a guarantee. Also due to the low recoil, small children have the ability to defend themselves from the walking dead. No more, "stay here Johnny, daddy will be back for you." Now you and your son can embark on a zombie blasting adventure that he will be bragging about for years to come! "My dad and I killed 500 zombies on our vacation to Colorado!"
