History of the .450 Express Magnum Cartridge:
North American Arms Company only produced 530 of these guns from 1981 to 1982.
The company had 50,000 to 100,000 Cartridge Cases produced by Winchester, based on the 45 Winchester Magnum Case, however rimless and slightly longer.
Only 20,000 cases were loaded, with Hodgen H110 powder and 260 grain SierraJacketed Hollow Point Bullet, before the firearm was discontinued.
In 1987 the company was sold,and in 1993/94 the new owners, had  all the  remaining  primed Cases Destroyed !
So only the first 20,000 cartridges were ever loaded, and most of them have been shot off. Truely Collectors item.
