JD Jones developed I believe the most successful line of "wildcat" cartridges for the Contender which turned the handgun hunting world around setting it full speed ahead.

Basically he came up with the "maximum yet safe" cartridge in about every caliber for the Contender package, developed several good loads for each, and then started chambering mostly Shilen barrels in basically any reasonable length, including rifle length, for his calibers. These were premium barrels and known for their quality and accuracy. Really nothing more need be said, his cartridges will forever stand on their own merit.

Let's see which of his cartridges we own and find out if we cover his entire line-up!

I will start with these two:
6.5 JDJ
375 JDJ

What do you guys have?
