It is a very low powered round, especially when compared to the more common .223, .308, .44, or .45 that are also used in the post-War world. The .22 was used as a commercial small game hunting round, but wasn't as common on the East Coast as the .32. It has a self-contained "rim fire" primer and cannot be used in the "breakdown" action to gain small pistol primers.
.22LR Hollow point
Hollow point bullets mushroom and break up on impact, causing massive trauma on fleshy, unarmored targets. However, this also means they break up when they hit things like armor plating, drastically reducing the weapon's penetrating power. Hollow point ammunition should be reserved for areas where heavily-armored foes are unlikely to show up; inside the casinos on the New Vegas Strip being one of the most obvious places.
Plinking is an onomatopoetic name, referring to the metallic 'plinking' sound of the ammunition as it hits tin cans or other, similar objects. Though less harmful than standard .22-caliber ammo, Plinking ammo can (usually) be found in abundance. A single Box of .22LR 'Plinking' ammunition will spawn 100 rounds when added to the player's inventory. Plinking ammunition works well in conjunction with the Silenced .22 SMG, where individual projectile damage can be made less of an issue than the volume of shots fired.
.22LR Round (Junk)
|The following is based on Fallout: New Vegas cut content and has not been confirmed by canon sources.|
The Junk Rounds perk from the Dead Money add-on was at one point intended to create ammunition of a special subtype. Called Junk or JNK, these rounds all provided the same modifiers regardless of caliber: 0.75x to Damage and 1.5x to Gun Condition. The rounds remain present in game code but are not placed in any locations, and if somehow obtained cannot be used in any weapons, even those chambered for the correct caliber.
Curiously, the presence of .22LR-caliber JNK rounds indicates that the perk was to provide a recipe for crafting .22LR rounds, though the final version of the perk does not include one.
