JD Jones sure is a neat guy to talk to.

I've only read articles where he was interviewed and his philosophies expressed. He obviously has a great insight on good ballistics. The Thompson folks make a bunch of barrels for his various JDJ creations. You have to be a reloader to really enjoy his work as the JDJ ammo is not off the shelf stuff. There's plenty of brass and die folks who support those boutique cartridges.
