Lynx family of cartridges

[nanuk]

anyone know what the Lynx family of cartridges are based on?

So far I've found the .222 Eichhorn Lynx, by googling. Also some Israeli artillery.

Neither the eigth or eleventh editions of Cartridges of the World have anything that I can find about it.

Google is not friendly when searching for lynx wildcat cartridge, by the way.

Ebay seller has some named that

I was kind of interested in them, but can't find info on a parent case.

Probably based off the 372 Fullbright.

the 222 Eichhorn Lynx is based on a shortend and fireformed 222 magnum

[Mk42gunner]

the 222 Eichhorn Lynx is based on a shortend and fireformed 222 magnum

Thanks for that info. Another wildcat that makes you go "What was he thinking?"

To me it sounds like it would do about what a .222 would do.

would likely be very close to the 223 and i think it was developed before the 223 so it wouldn't be that crazy of an idea at the time

5.7 x 43 (.222 Eichorn Lynx)

This is a cartridge developed by Dr. Edgar L. Eichorn of Arcadia, California otherwise known as the .222 Eichorn Lynx. It is sort of an "improved" .222 but the length of the body is the same as the .222 Magnum without the neck shortened so that the overall length of the case is the same as the .222 Remington. This blown-out version uses the common minimum body taper design with 40-degree shoulder. It has proven to be a very efficient little cartridge. Cases are easily made by simply shortening the standard .222 Remington Magnum to the proper length of 43mm and then fire forming in the usual manner, so common with other "improved" cartridges, in rifles which accept factory loads. This cartridge could easily become of interest to bench rest shooters because of its high flexibilty and exceptional accuracy.

I don't think there were any more members of the "family"; neither my edition of Ackley nor THMCC show anything else by Eichorn.
