Brenneke slugs

[Teaman1]

Is there any difference between the Brenneke sfmbpm and the Brenneke black magic slugs?
Just talking about the projectile. I’m struggling to find a direct comparison. I emailed brennekeUSA and I’m not getting a response.
Main purpose for me would be grizzly defense
(basically just to make me feel better haha)

I have shot only deer and elk with the Green Lighting, and Magnum Crush (rifled barrel) and they smoke them. The Green Lighting pack a hard hit on WT and elk. Drop them in their tracks dead. I have confidence it would slay a grizzly with no issues.
I live in griz country and just use the Green Lighting anymore. They can be shot out of smooth bore and rifled with accuracy. I pack them upland bird hunting JIC. I also have never got a response from Brenneke when inquiring about availabity of the Black Magics.

On that note, maybe I’ll just roll with the green lightening haha
