These bullets are awesome against the heavily armored Gearhead Clan in the Eastern Wasteland. Even after hitting their target, Fat Mammas keep traveling, puncturing anything along their flight path. These powerful bullets (costing $8 per round) can punch through any amount of armor, inflicting massive damage. When you need even more stopping power, construct some Fat Mammas. Fatboys aren't cheap, costing more than $2 per shot, but they have the stopping power to kill most unarmored enemies with one hit. While Killbursts ammo increases the weapon's rate of fire significantly, it must be reloaded after each trigger pull, making it largely ineffective in frantic engagements. Killbursts ammo basically turns the weapon into a machine pistol, automatically firing a burst of bullets with each pull of the trigger. When loaded with standard Pistol Rounds, the Settler Pistol is mediocre at best, inflicting minimal damage to bandits and mutants alike. This makes it much easier to score headshots on distant enemies during firefights. Simply place the crosshairs over your target and squeeze the trigger. While the pistol has its own iron sight when aiming, the Monocular is a far more accurate telescopic sight. Before buying anything else, purchase the Monocular to assist in aiming.
