Brenneke Slug Review
I have used .410 Brenneke slugs for two years now and find them to be extremely accurate. 3″ shotgroups at, ready for this, 75yards! That was from my Mossberg 183K with the accu-choke on “Modified”. The Brenneke is a 1/4 oz., 3″ Magnum slug load that boasts a “Practical Sight in Range” of 88 yds!
The Brenneke slug was invented by the German gun and ammunition designer Wilhelm Brenneke(1865–1951) in 1898. The Brenneke slug is a solid lead slug with fins cast onto the outside. The fins do not impart spin, but serve to lessen the contact area within the bore, therefore increasing velocity. A plastic, felt or cellulose fiber wad attached to the base remains after firing. This wad serves both as a gas seal and as a form of drag stabilization. Similar in theory to the Foster Slug with it’s hollow base and “Weight forward” design. But Since the Brenneke slug is solid, rather than hollow, the Brenneke will generally have less deformation on impact and will provide deeper penetration.
At the pit today I shot two Brenneke slugs from my Mossberg 500. The aiming point was the “D” in “FORD” that was on an old tailgate from a Ford pickup truck. At 40 yards, from a full-choke, and with only the bead sights, I placed two shots within 2 inches of each other. The surprise was that the tailgate lay against the sand pile at a 60 degree angle and those slugs tore one inch holes in the Metal on impact and severely dented and split the other side of the tail-gate. Why was this so surprising? The tail-gate was from a late sixties or early seventies pick-up! So I would gauge the metal at 18 or better ( I am not a metalist or an auto buff so if someone can give a better idea of the metal thickness it will help). Therefore I suspect that a Brenneke would EASILY travel through most vehicle doors today when struck at a decent angle of trajectory. I will post some pic’s tomorrow of that tail-gate when I return for a second round of shooting. This time with my 148 grain slugs being pushed with 11grains of Red-Dot.
