This is B&P’s 3.5-in. shell. One gets a 2 ¼-oz. payload of NICKEL-PLATED pellets in various shot sizes at a substantial 1170 fps. Maximum payload for tremendous energy transfer is the advantage for this cartridge. This has applications for turkey hunting, predators and personal defense. Talk about pattern density, this is a black fog of large pellets on target! (To convert from grams to ounces, multiply by 0.03527.)
