TAOFLEDERMAUS is back with another prototype shotgun slug built by the Ballistic Machinist, Tim Hamilton. These dumbbell slugs are absolutely brutal. They’re surprisingly accurate for such an odd shape and cut through level III Kevlar like a hot knife through butter. Tim expected the slugs to tumble more than they do. Everyone was surprised when the dumbbell rotated once in air then flew sideways in a straight line toward the target. They are very similar to an earlier concept that didn’t quite perform as intended. These new and improved dumbbells are pretty hefty weighing in at 40 grams a piece. The resulting wound cavity is absolutely devastating.
