The Black Aces Tactical 12 gauge ammunition utilizes 2-3/4″ high-brass shells. As you probably know, high-brass refers to the length of the metallic base but doesn’t necessarily mean it’s made of brass. Just like the majority of shotshells currently available on the market, the Black Aces Tactical shells also have steel heads plated with a corrosion-resistant metal, zinc in this case. The roll crimped hull mouths are slightly tapered which is a great feature ensuring a much more reliable feeding when using the ammunition in manual repeating (e.g. pump-action) or autoloading shotguns. The overall load weight is 1-1/5 oz and the advertised muzzle velocity is 1,425 fps.
