Remington HD Ultimate Home Defense Round anyone familiar with the duplex mixture of # 2's and 4"s? http://www.remington.com/products/ammunition/shotshell/home_defense/ Remington HD Ultimate Home Defense shotgun ammunition features the same pellet material as the popular Wingmaster HD™ tungsten-bronze hunting ammunition and is offered in two loadings. Consumers can choose from a load of BB’s for the highest terminal energy or a duplex mixture of #2 and #4 pellets for excellent pattern density and outstanding stopping power with a reduced chance of over-penetration. Both loads are 12 gauge, 2 ¾-inch with 1 1/4 ounces of shot at 1250 feet per second. At the most commonly encountered home defense distances, Remington HD Ultimate Home Defense produces very tight patterns for one-shot confidence. HD Ultimate Home Defense ammunition is the perfect compliment to Remington’s recently expanded line of tactical shotguns. Recent additions to the line include the Model 870 Express® Tactical with XS® Ghost Ring Sights and the Model 870 Express Tactical with Gray Powder Coat Finish. Both shotguns are 12 gauge and feature 3-inch chambered 18 ½-inch barrels which are threaded for the included Tactical Extended Rem™ Choke. Average weight for both models is 7 ½-pounds, overall length is 38 ½-inches and both guns are equipped with a black synthetic stock and fore-end. Wanna kill these ads? We can help!
