The new 4.5mm BBs shatter just like frangible bullets upon impact with hard surfaces, thus minimizing the risk of ricochets for which conventional steel BBs are notorious. The new BBs are made entirely of lead-free material. Both properties together make them much safer for indoor shooting. The frangible BBs are made of a special sintered alloy and weigh 0.29 grams, which is less than the 0.36 grams of common steel BBs. The Dust Devil BBs are about 10% faster due to this slightly lower weight. The BBs are magnetic and therefore usable in weapons with magnet-operated magazines. Air Venturi, the manufacturer of these revolutionary BBs, has given H&N Sport the general agency for Europe (excluding UK). The Dust Devils are offered by H&N Sport in two packages: 1,500 pieces in a novel cardboard box with filling aid, and 750 pieces in the proven screw-on tin. Dust Devils are made in the USA and are patent pending.
