The '''.12 Eichelberger Long Rifle''' is a wildcat cartridge created by [[Bill Eichelberger]] in 1982 and was made for short to mid-range small game and target shooting. The cartridge is a .22 Long Rifle casing, necked down using a series of dies, to finally accept a .123 caliber projectile. It is one of the smallest wildcat cartridges to ever exist, with the exception of Bill Eichelberger's [[.10 Eichelberger Long Rifle]], which he would later create in 1999.

Being a rimfire cartridge, it can basically only be fired once. As a result, the process of very carefully loading a custom power charge, necking down the case using a series of dies and annealing, trimming, and finally seating the tiny .123 caliber bullet becomes a significant task. As a result, it's largely a novelty.

== Ballistics ==

From Eichelberger himself, in [[Cartridges of the World]]: The .10 Eichelberger Long Rifle contains a 7.2 grain bullet with 1.8 grains of AA9 powder. This reaches a velocity of 2,160 feet per second for 74 ft lbs of energy.

== Conversions, Custom Barrels, Projectiles ==

According to Frank Barnes' book series [[Cartridges of the World]], the .12 Eichelberger Long Rifle "...works well with 22-inch barrels having a rifling twist of 1:5. Suitable actions to rebarrel and chamber for the .12 Eichelberger Long Rifle include modern .22 LR bolt actions, and single shots such as the Thompson/Center Contender and G2.

It appears that [[SSK Industries]] was supplying .12 barrels and appropriate projectiles for loading this cartridge on custom order basis, though it's unclear if they still offer these items after being acquired by [[Lehigh Defense]].
