Firing a .375 JDJ in a .444 or a .338JDJ in a .375 will cause no safety hazard. The bullets are smaller than the bore so pressure and velocity will be way down.

Don't let the armchair experts tell you it is a bad idea. The practice is not unsafe, IHMSA shooters used to shoot thousands of .223s in their 7 TCU barrels to fire form them, never a problem.

Take too it! Not a problem and you can sub small pistol magnum for the rifle primers in the .454 brass if you have pressure concerns you.


Good info, thanks guys!

Carpe Diem, I've always wondered about that on the 375JDJ fired in a 444 Marlin issue. I always wondered if the bullet would travel straight and exit the barrel or if the neck blowing back out to 444 Marlin dimensions would affect its flight. Hopefully after I'm gone it never happens. My son will get my guns so at least he will know better.

Experience is the best teacher, hunger good sauce.
