I use it for Deer Season in NY, out of Single Shot HnR 12 gauge. Amazingly accurate and one hell of a punch for a single shot all you need. Never had a deer go more than 30 yards with the Black Magic.

About Brenneke USA 12 Gauge
Brenneke Black Magic shotgun shells are built around a lead rifled slug, a CleanSpeed coating, and the patented B.E.T. wad system.
In general, slug ammunition sends a solid projectile rather than a shot pattern, making it a common choice when a shotgun is used for hunting with focused impact. This Brenneke Black Magic Magnum slug is intended for demanding hunting applications, including deer, bear, and other dangerous game.
The load is compatible with rifled or smoothbore barrels, and it should be used only in shotguns chambered for the shell length shown in the product title.
