About the 458 SOCOM Wildcat

In the years following the great ammo shortage of 2013, Black Butterfly Ammunition was born.

The initial offering was determined to be the .458 SOCOM Wildcat because of its awesome, unprecedented reputation.

This round was first developed by Marty Ter Weeme, founder of Teppo Jutsu, LLC in 2000, and quickly developed a cult-like following among big bore shooters and hog hunters due to the stellar power and accuracy it delivered.

“The impetus [for developing the .458 SOCOM] was an informal (“beer and barbeque”) discussion with a senior member of the US special operations community regarding the apparent lack of effectiveness of the 5.56 x 45 cartridge in recent war usage. In particular, reports from the Task Force Ranger in Mogadishu, Somalia complained that multiple shots were required to neutralize members of the opposing force, leading to a formal request to develop a new cartridge that would deliver far more energy from short barrels at relatively short distances. After the design was completed, Tony Rumore of Tromix Corp in Broken Arrow, Oklahoma was contacted to build the first prototype. Based on the ensuing favorable reviews, commercial production started, and the initial rifles were produced by Tromix. Currently, several firms offer rifles or upper assemblies in this caliber, including AR-15s, AK-47s, single shot and bolt action rifles.”

Development with Nationally-Known Projectile Manufacturers

This Big Bore round fit with the business philosophy of the Black Butterfly Ammunition founder Nick, who wanted to manufacturer premium hard-hitting ammunition for hunters. During testing, it was quickly discovered that there were not enough dedicated .458 SOCOM projectiles – many were retooled .45/70 projectiles that were also were too blunt, reducing the ability to “hang out” the rounds. During the first year of manufacturing, Black Butterfly Ammunition formed relationships with several nationally known projectile manufacturers to develop exclusive projectiles specifically for the .458 SOCOM, such as the CTX Migration, Maker Turbo Saw, Cutting Edge Maximus Giganticus, and the Hawk D600 Colossus to name a few.

Recognized as the Industry Expert

Black Butterfly Ammo was quickly recognized as an expert in the 458 SOCOM sector and was asked to work with CMMG on the release of their CMMG Anvil rifle. During the release, Black Butterfly Ammo was fortunate enough to be reviewed and featured in multiple national magazines and articles – including Guns and Ammo, Gun World and American Rifleman Magazine.
