375jdj Accuracy Loads
The following information has been provided by the creator of this cartridge, J.D. Jones:
The .375 JDJ is "made by simply running a .444 case through the .375 JDJ full length sizing die, the .375 is exceptionally easy to make. It headspaces on the shoulder but will headspace off the rim, too. Full charge loads are loaded the first time around. No fireforming is necessary. Firing a full charge load in unfired brass is comparable to firing factory ammunition in anything.
"In loading this cartridge — and a lot of others for that matter — disregard the cannalure. Seat the 220s, 260s, 270s, and 285s with the base of the bullet seated to the end of the neck. Heavier bullets should be seated at least 0.025" away from the lands.
"I've used this one on all huntable continents except South America which I intend to rectify in April of '94 on animals of practically all sizes and I have no intention of switching. When I'm serious about killing something big this is the one I take."
Editor's Note: The .375 JDJ has the distinction of being the cartridge that blew the outer framework off the gun port in our ballistic lab.

Hunting Mastery Selected Tips
Deer hunting is an interesting thing that reminds you of those golden old ages of 19th centuries, where a handsome hunk well equipped with all hunting material rides on horse searching for his target animal either for the purpose of displaying his masculine powers or for enticing and wooing his lady love.
