![]() The secant ogive on Scirocco bullets requires some experimenting to find the correct distance from contacting rifling for the bullets to shoot accurately. The bullet had expanded widely, yet held onto 135 grains of its initial weight. The bullet had turned both lungs into soup and stopped against the hide on the far side. I hit a bull elk through the ribs standing broadside at about 100 yards with that load, and the elk wobbled a few steps and pitched over on its nose. 30-06 the 150-grain Scirocco has a muzzle velocity of 3,082 driven by 60.0 grains of Norma Universal Rifle Powder. Those same Sciroccos still hold together with increased velocity. Both of the deer fell dead on the spot, with holes the size of a fifty-cent piece through the ribs behind the shoulder and out the far side. I handed the rifle to my son and he shot a second doe. I leaned against a tree and brought the Savage up and shot one of the does when it stepped into the open. At the last of shooting light one November evening, my son and I stood side-by-side watching a band of whitetail does. The bullet’s velocity is only about 2,600 fps when it leaves the 20-inch barrel of my Savage 99 rifle, yet it still expands widely at the 2,300 fps it slows to at 150 yards. The 150- grain Scirocco is a great deer bullet fired from my. Sciroccos expand violently, increasing the terminal effect of more sedate cartridges. 25-06 Remington shot 100-grain Scirocco bullets somewhat over an inch at 100 yards. A plastic tip in the hollowpoint lessens air resistance in flight and initiates expansion on contact with game.Ī Ruger M77. The jackets are quite thick near the tip and increase in thickness along the shank. 24-caliber Scirocco and nearly 63 percent of a 150-grain. The jacket comprises approximately 71 percent of the weight of a 90-grain. The copper jackets are heavy and thick, too. “That makes the bullets good out to 800 and 900 yards,” Hober said. The bullets expand at impact velocities down to 1,750 fps and stay intact at velocities up to 3,200 fps. The result is today’s Sciroccos still expand into a wide mushroom, but the expanded portion of the bullet and more of the shank remain intact for deeper penetration at high-impact velocities. What changed was the metallurgy of the copper jackets that have been annealed to better withstand high-impact velocities. ![]() “The inside and outside shapes of the original and II are the same,” Hober said. (Enough time has passed that I’m going to just call them Sciroccos.) The bullets are constructed the same way and on the same machines as the original bullets. 30-06 rifle.Ībout 2006, Swift redesigned the bullet to better withstand high-impact velocities and called it the Scirocco II. Swift 165-grain Sciroccos paired with IMR-4831 provided this group at 100 yards shot from a Ruger American. The mushroomed bullets often had a split in the jacket or had expanded out nearly flat. Instead, he started receiving reports of hunters using these magnum cartridges shooting Sciroccos at game at 50 yards or so. “I thought people with these big magnums would be mostly shooting big game at long range,” Hober said. 300 Remington Ultra Magnum, were introduced. 507 BC for Nosler 180-grain AccuBond bullets.Ī few years after Sciroccos reached the market, quite a few mega-magnum cartridges, such as the. 552 BC for the Berger 6.5mm 130-grain VLD Hunting bullet. For example, Scirocco 6.5mm 130-grain bullets feature a. Hober said original Sciroccos were really the first long-range hunting bullet on the market, “and were good out to 1,000 yards.” To aid in that long-distance shooting, the Scirocco’s polycarbonate tip, secant ogive and 15-degree boat-tail creates bullets with a high ballistic coefficient (BC). “What does zinc do to copper? The same with antimony added to lead, it makes it brittle.” Pure copper and lead, though, are more elastic to better withstand the stress of expansion at high velocity. “Most bullet jackets are made of copper with the addition of zinc,” said Bill Hober, Swift’s CEO. ![]() Swift began developing Scirocco bullets in 1997 and introduced the bullets in 1999, made with a pure copper jacket bonded to a pure lead core. The box the bullets are packaged in is the only visible difference between original Scirocco bullets (right) and Scirocco II bullets.
