Looking at a bolt gun but it's a pretty neat cartridge. Per Ken Waters, it's nothing special and there's lot of others what do much the same but still....

The only problem with using that or the .375 JDJ in a Winchester or Marlin is you are limited to short nose bullets. Most .375 bullets are fairly long and tend to make an unmanageable OAL when seated in a full length .444 case necked down for the lever actions.

The .375 JDJ is an excellent carbine cartridge. Roger uses one in a contender carbine and has killed a bunch of stuff with it. His wife carried it to Africa last year and shot several plains game.
