Description
Federal Power-Shok .303 British ammunition combines solid hunting performance with a sensible price tag. This load uses a 150-grain jacketed soft point bullet designed to expand reliably on impact, making it suitable for medium-sized game at reasonable hunting distances.
What Makes This Federal Load a Good Field Choice
The 150-grain soft point bullet is built with a hot core process that keeps the lead core and jacket properly bonded, so you get consistent expansion without core slippage. The bullet's fluted tip design helps ensure reliable performance across a range of impact velocities. At 2690 fps muzzle velocity and 2410 ft-lbs of energy, it provides a good balance of penetration and expansion for ethical hunting.
Built on Dependable Federal Brass
Each round sits on quality brass cases with reliable Federal primers and powder. The non-corrosive construction means you can shoot without worrying about bore damage, and the cases are reloadable if you want to handload down the road. This ammunition is new production and boxer-primed, making it simple and straightforward to work with.
Suited for Classic and Contemporary Rifles
Whether you're using an older Lee-Enfield, a sporterized surplus rifle, or a newer rifle chambered in .303 British, this ammunition feeds and functions reliably across the board. The load works well for hunters who appreciate the history and character of the .303 cartridge while still wanting straightforward, field-ready hunting ammunition.

Frequently Asked Questions
What game is Federal Power-Shok .303 British 150gr suitable for?
This load is designed for medium-sized game including whitetail deer and similar-sized animals. The 150-grain soft point provides good penetration and expansion at typical hunting ranges. It can handle larger game like elk when shot placement is precise, but it's specifically tuned for medium game between 50 and 300 pounds.
Is this ammunition corrosive and can I reload the cases?
No, Federal Power-Shok uses modern non-corrosive primers, so you don't have to worry about bore damage after shooting. The brass cases are boxer-primed and fully reloadable, making this a good option if you handload or plan to get into reloading.
How does this ammunition perform in older rifles like Lee-Enfields?
Federal Power-Shok is designed to work reliably across the full range of .303 British rifles, including military surplus and sporterized models. The load is mild enough to function smoothly in older actions while still delivering effective hunting performance. Many users report consistent feeding and good accuracy in classic rifles.
What's the difference between the soft point bullet and other hunting rounds?
The soft point design expands on impact to create a larger wound channel, improving stopping power on game. Unlike full metal jacket military rounds, the soft tip allows controlled expansion for quicker, more humane kills. Federal's hot core process ensures the bullet expands reliably across a range of distances and impact velocities.
