For deer, antelope, and elk hunters who need reliable terminal performance across varied ranges, the Grizzly Cartridge Trophy Grade 270 Winchester 130-grain Swift Scirocco II delivers. Chambered in 270 Winchester and loaded with a bonded polymer tip projectile, this round launches at 3200 feet per second with 2956 foot-pounds of energy at the muzzle. The secant ogive profile and 15-degree boat tail maintain a ballistic coefficient of 0.45, flattening trajectory and reducing wind drift on shots past 300 yards.
Built for the Hunt
Grizzly Cartridge Company hand-inspects each manufacturing stage — from case prep through final assembly — ensuring consistent charge weights and seating depth. The Swift Scirocco II bullet uses an internally bonded lead core and tapered jacket wall, expanding predictably while retaining over 70% of its mass through heavy muscle and shoulder bone. That sectional density of 0.242 drives penetration on quartering shots where cup-and-core designs may fragment.

Brass cases accept standard large rifle primers for handloaders who want to tailor seating depth or powder charges to their rifle’s chamber. This load pairs well with bolt-action platforms in 270 Winchester — particularly those with 22- to 24-inch barrels where the case’s efficiency peaks.
