NOTICE: This round requires a can (suppressor) and or an adjustable gas block to reliably function and lock back the bolt on the last round. If you don't have one, you will need to lock back your bolt before switching mags. 

If you don't have a can and only an adjustable gas block, get a sample and get it a try!

These are crazy fun to shoot!

About Us

Our main company goal is to produce an excellent product that will operate efficiently and effectively in your firearm.

The Black Butterfly Ammunition Company was created to meet the needs of the discerning specialty shooters who prefer quality over cheaper than dirt, mass produced, factory ammunition.

Each round produced by The Black Butterfly Ammunition Company is hand manufactured and individually inspected by a loading expert to insure that we produce the finest quality ammunition available. This includes visual inspections and appropriate case gauge testing of each round produced. In addition, we randomly sample and shoot our production loads at our onsite range, this way we can ensure it will meet our stringent requirements and will function properly in your firearm.

Our loading and manufacturing expertise comes from years of hands on manufacturing and production experience with industry leaders like Colt Manufacturing Company, Kahr Arms and aerospace and defense giant, Esign-Bickford.

The Black Butterfly Ammunition Company warrants the original consumer purchase for 1 year from the date of purchase. At our discretion, we will replace or refund the original purchase price provided a proper proof of purchase is submitted. Our warranty will be free of charge except for any shipping charges that might be incurred by the customer to return their product to our facility. Of course, this warranty does not cover product abuse such as neglect, reloading, and or any other issues caused by improper handling.


Premium, .458 SOCOM, 300 gr, 20 Rounds, CTX Migration Lead Free Frangible, SUBSONIC PLINKER (1 BOX LIMIT)

This round was created for target and or close quarters training applications. Due to the fact the projectile is lead free, it can also be used in lead free ranges and in states like California that are gradually phasing out lead projectiles.

This monsterous projectile was designed to allow this round to realiably cycle an AR with a can and or an adjustible gas block. The shape of this projectile also insures it will feed properly from any standard GI mag on the market.

This is an exclusive product manufactured by CTX to Black Butterfly Ammunition’s specifications.

This projectile is also offered to the public for reloading exclusively through Black Butterfly Ammo.
