The Mighty Armory GOLD MATCH .300 Blackout Sizing Decapping Die is a Precision Match Series Sizing Die designed to size and decap cases for reloading .300 Blackout ammunition. The Gold Match rifle sizing die is a Precision Match Series sizing, decapping die offering full-length headspace and concentric sizing to SAAMI specification, easily adjustable with a simple turn of the die on your press.
Mighty Armory's Gold Match Rifle Reloading Dies are precision machined from high-grade tool steel with tight tolerances to ensure consistent, uniform sizing and perfect vertical alignment. Our rifle reloading dies are single point cut finish with an extremely smooth sizing bore at 60 Rockwell hardness. A hard, smooth sizing surface that is consistent in sizing, especially head-spacing is of the utmost importance when reloading precision ammo.
The one-and-done sizing of your .300 Blackout brass will be effortless. Easily decap and resize over a million cycles. Adjust the die in your press by turning it up or down to easily set shoulder bump from zero to -.005.
The drop-in mandrel shaft is Swiss-machined, heat treated to 50 Rockwell, and extremely durable. The internal threads will accept either a decapping pin or pointer. The pointer is a unique design that protects the threads of the shaft and also acts as a guide during case sizing.
Resizing cases with the Mighty Armory Gold Match .300 Blackout Sizing Die will yield the precision ammunition you're looking for. Accurate sizing with Mighty Armory reloading dies enhances the safety, reliability and accuracy of your ammunition. The extended, full length size area prevents both under-sizing and over-sizing the case at the neck, shoulder and base. This will result in proper case pressure, cleaner powder burn, reliable chambering and extraction, absolute accuracy, and extended brass life for more reloads.
Full length sizing is recommended for all rifle cases as neck sizing can lead to overexpanded cases and reduce reloading times due to weakened brass.
*All Mighty Armory rifle sizing decapping dies now include the primer flicker cap and spring to prevent primer pullback.
