These weapons (rifle or pistol) fire a round no wider than a few millimeters and no longer than an inch. In an attack by the undead .22 rimfire stands proudly alongside its heavier cousins. The small size of its rounds allows you to carry three times as much ammunition. this also makes the weapon itself lighter, a godsend on long treks through ghoul-infested territory. Two disadvantages present themselves, however, when the use of a .22 is considered. The small round has zero stopping power. A ghoul taking a round to the chest would not even be slowed. Another problem is the lack of skull penetration at longer ranges. But do not discount this small and efficient firearm.
