XTRA Speed cartridges contain no lead. A judicious mix of bismuth and steel allows you to benefit from the best of both materials. Bismuth is easily deformed, allowing maximum energy transfer, even on game protected by thick layers of feathers. As for the steel, it gives the hunter firing the XTRA Speed cartridge an even spray, with no nasty surprises. The 34 grams of the charge are expelled at 442 metres per second. The steel pellets are n°4 while the bismuth pellets are n°5. Available in 12-gauge.
