The 358 JDJ was developed from the
444 Marlin by necking it down to .35" caliber, with a steep shoulder angle.
The 358 JDJ was developed in 1978 by
Mr. J.D. Jones of SSK Industries for the Thompson/Center Contender single shot pistol or rifle with a special 15"
SSK barrel.
These cartridges were produced by Quality Cartridge Company, so they are considered
a proprietary cartridge not a wildcat cartridge, unless you make your own by
fire-forming or have very expensive
reloading equipment.
