Before writing off shotgun slugs completely it might be worth doing some penetration tests with the Brenneke "magnum crush", which throws a 1.5 ounce {666 gr.} slug at 1600 fps with 3800 ft. lbs. of muzzle energy and particularly the Brenneke "special forces maximum barrier penetration magnum" which throws an extra hard alloy 1 3/8 oz {602 gr.} slug at 1650 fps with 3545 ft. lbs. muzzle energy. No doubt either would far out penetrate a Foster slug or any of the old 1 - 1 1/4 oz. Brennekes.
Since I don't have a rifled barrel, I'll stick with my well-stocked Brenneke Black Magics!
Anyone that thinks brenneke slugs are “The Ticket” needs to find and read member klikitarik’s post about a brenneke failure vs. a small/medium brown bear.
