Federal Power-Shok 308 Winchester 150 Grain Jacketed Soft Point ammunition delivers field-proven terminal performance for deer, hogs, and medium-size game at hunting ranges out to 300 yards. The 150-grain jacketed soft point bullet exits the muzzle at 2820 feet per second, carrying 2648 foot-pounds of energy — enough momentum to drive through hide, bone, and vitals while expanding reliably in soft tissue. Federal Power-Shok loads use brass cases, non-corrosive boxer primers, and consistent powder charges to maintain shot-to-shot velocity spreads under 50 fps in factory testing.
Performance at a Glance
Federal chambers this load in new-production brass cases with boxer primers, making spent cases reloadable for handloaders who want to reclaim components. The jacketed soft point projectile features a lead core with a partial copper jacket that exposes the nose — during impact, hydraulic pressure deforms the exposed lead, initiating expansion while the jacket controls fragmentation. Velocity stays supersonic beyond 400 yards, simplifying holdover calculations and reducing wind drift compared to slower hunting loads.

This load balances flat trajectory with controlled expansion — the 150-grain projectile sheds velocity more slowly than lighter varmint bullets while delivering more energy on target than 180-grain options at extended range.

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.
- Follow the four universal rules of firearms safety: treat every firearm as loaded, never point at anything you don’t intend to destroy, keep your finger off the trigger until sights are on target, and identify your target and what lies beyond it.
- Verify current ammunition restrictions in your state, county, and municipality before ordering — some jurisdictions prohibit lead projectiles, limit purchase quantities, or require background checks for ammunition transactions.
- This product 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 and avoid exposure to combustion residue at indoor ranges without adequate ventilation.
