The Swift High Grade 7mm Remington Magnum load delivers precision hunting performance for medium to large game at extended ranges. Chambered in the proven 7mm Remington Magnum cartridge, this ammunition combines a 150-grain Scirocco II bonded polymer tip bullet with hand-inspected brass cases that meet or exceed SAAMI specifications. Each round generates 3036 feet per second from a 24-inch test barrel with 3070 foot-pounds of muzzle energy. The secant ogive bullet profile and 15-degree boat tail base create a sleek aerodynamic shape that maintains downrange velocity, while the bonded core construction ensures structural integrity through bone and tissue. For hunters pursuing elk, mule deer, or similar-sized game across open country where long shots are expected, this load balances flat trajectory with terminal performance.
Built for the Box
Swift manufactures this ammunition with individually chambered and sized cases to ensure proper fit in SAAMI-specification chambers. The Scirocco II projectile features an internally bonded lead core within a tapered jacket wall. This construction method prevents core-jacket separation during expansion, a common failure mode in conventional cup-and-core bullets when striking heavy bone or dense muscle at magnum velocities. The polymer tip initiates expansion at impact while the boat tail design reduces aerodynamic drag in flight. Brass cases are reloadable with non-corrosive Boxer primers. Each case receives HERNON water-tight sealing at the case mouth and primer pocket to protect propellant from moisture during transport and field carry.

The 0.515 ballistic coefficient places this projectile in the high-performance category for 7mm bullets at this weight class. Expect retained velocity sufficient for ethical shot placement on deer-sized game beyond 400 yards when fired from rifles with appropriate barrel lengths and twist rates. The 150-grain weight provides a favorable balance between sectional density (0.266) for penetration and reduced recoil compared to heavier 7mm loads.

Safe Handling & Compliance
Federal law requires purchasers to be at least 18 years old for rifle and shotgun ammunition, and at least 21 for handgun ammunition. Ammunition cannot be shipped to certain states, counties, and cities — review our ammunition shipping restrictions before ordering. Store ammunition in a cool, dry location away from heat sources and out of reach of unauthorized users.
- Always keep the muzzle pointed in a safe direction. Treat every firearm as if it were loaded. Keep your finger off the trigger until ready to fire. Be certain of your target and what lies beyond it.
- Verify that ammunition caliber matches the chambering stamped on your firearm’s barrel or receiver. Firing incorrect ammunition can cause catastrophic firearm failure, serious injury, or death.
- This ammunition contains lead, a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands thoroughly after handling ammunition or cleaning firearms. Pregnant women and children should avoid exposure to lead residue at shooting ranges.
