The .10 Eichelberger Long Rifle. It is based on the .22 Long Rifle, necked down to accept .103 caliber bullets. It has been said to be the smallest wildcat cartridge ever made.

The .10 Eichelberger Long Rifle is a wildcat cartridge created by Bill Eichelberger in 1999 and is claimed by Frank Barnes' book Cartridges of the World to be the smallest wildcat cartridge ever made. It is based on the .22 Long Rifle, which is necked down to accept a .103 caliber bullet.

As is the case with rimfire cartridges in general, each round can pretty much only be fired one time. As a result, necking down each round, seating a bullet and so on without the ability to reload, makes this a very laborious round to set up.

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.
