6,5x46 Mason

Do anyone have information on the new 6,5x46 Mason cartridge? It has a “Hornady look” and is possibly made for one James Mason of Las Vegas, NV.

Bullet dia.: 6,7 mm (.264")
Rim: 9,5 mm (.374")
Head: 9,4 mm (.370")
Case length: 45,8 mm (1.803")


It is a Hornady product. I believe it was produced for someone wanted to sell it to the military.
