The Swift Scirocco II in 7mm .284 150 grain is one of those bullets that does a little bit of everything well. It pairs a bonded copper jacket with a lead core, then caps it off with the Signature Black Tip, so you get a slippery, high-BC projectile that still opens up and holds together once it hits game. For anyone loading up a 7mm Rem Mag, 7mm-08, 280 Ackley, or just about any .284 caliber rig, this is a proven medium and big game choice.
The shape here is the real story. A secant ogive, long sleek profile, and a 15 degree boat tail give this 150 grain pill a G1 ballistic coefficient of .515 with a sectional density of .266. That translates to a flat trajectory and strong retained velocity and energy out past where a lot of bullets start to run out of steam. The polymer tip cuts drag in flight and gets expansion going on contact, which is a big part of why the Scirocco has a reputation as a dependable long-range hunting bullet.
This is a bonded bullet, meaning the copper jacket is fused to the lead core so the two don't separate on impact. The jacket is thick and tapers along the shank, controlling expansion across a wide velocity window. In the field these bullets reliably expand at impact speeds down to around 1,750 fps while staying intact at velocities up to roughly 3,200 fps, so you get a wide mushroom and deep penetration whether the animal is close or way out there. Real-world recovery on elk has shown this design hangs onto a strong percentage of its original weight.
A few things worth knowing at the bench. This bullet runs long, measuring about 1.385 inches, and it carries a generous bearing surface against the rifling. Because of that longer bearing surface, it often likes slightly lighter maximum charges than other bullets of the same weight and diameter, so start low and work up like always. Seating depth has never been a headache with these, and a little experimentation with COAL usually tightens groups up nicely. Always consult current published load data for your cartridge before loading.
These .284 diameter bullets are built for any 7mm caliber you reload, including 7mm Rem Mag, 7mm-08 Remington, 280 Remington, 280 Ackley Improved, 28 Nosler, and 7mm PRC. At 150 grains they strike a nice balance of high BC and moderate recoil, which makes them a versatile pick for deer-sized game on up to elk.
Yes. The lead core is bonded to the copper jacket using Swift's proprietary process, so the two stay together on impact. That bonding is what gives the Scirocco II its high weight retention and deep, controlled penetration across a wide range of impact velocities.
With a .515 G1 ballistic coefficient and that sleek polymer tip and boat tail, it flies flat and holds velocity well downrange. The tip initiates expansion even when impact speeds drop off at distance, with reliable opening down around 1,750 fps, making it a solid long-range hunting bullet.
They load like a standard premium hunting bullet, but the long bearing surface can mean they prefer slightly lighter maximum charges than other bullets of the same weight. Always start low, work up, and reference current published data for your specific cartridge. Playing with seating depth is also a good way to fine-tune accuracy.
