The Mighty Armory Magnum Decapping Die is a universal decapping die recommended for use on all single stage and turret presses.

Mighty Armory’s innovative decapping die design utilizes a spring-loaded primer flicker. The spring and cap design allows upward shaft movement before contacting a stop. The rebound of the spring forces the shaft down and flicks the primer off the pin, shooting it through the press funnel and eliminating primer pullback. 

100% precision CNC machined with heat treated and tempered tool steel shaft and pins.

The Magnum Decapping Die includes two .078 diameter pins, which will decap standard and military brass. It is important to know the size of the case flash hole diameter when selecting your Decapping Die. For decapping cases with small flash hole, check out the PUA decapping die with .058 pins.

Perfect vertical alignment. The Magnum die will decap .380 ACP cases up to 3" long cases and .545 wide. Bore is .600.

Mighty Armory reloading dies are designed to be ultra tough, with comprehensive, ease of use and tool-free assembly. Will easily decap any boxer primed, crimped military case.

The Magnum decapping die includes two (2) steel .078 decapping pins, for all standard .080 flash hole diameters. Toughest in the industry. The Mighty Armory decapping pins have a 1,000 pound bend rate. 

No more interrupted loading days. 

Magnum vs PUA Decapping Dies:

The difference between the Magnum Decapping Die and the PUA Decapping Die is the diameter of the decapping pin.

Exchangeable pin:

Mighty Armory decapping pins can be exchanged on the depriming shaft. Easily switch for Lapua, Alpha & Peterson Brass profile flash hole with the .058 Decapping pin. Simply swap the pin on the shaft.

Pro Tip:

All Mighty Armory Decapping Dies can also function as Case Hold Down Dies by simply switching out the pin on the shaft for a Universal Hold Down Tip!
