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.

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.
