Fusion Vs. Power-Shok

Share on Social Share on Facebook Share on Twitter

These two proven Federal rifle ammo offerings have been filling deer camp buck poles and notching tags all over North America for years. The two have several similarities, but also some important differences. Which is the best rifle ammo? The answer really depends on you—the cartridges you shoot, the country you hunt, the specific game you’re after and the kind of shots you expect to take. Hover over the points on the image below to see the construction and performance aspects where Fusion and Power-Shok share common ground and where they differ.

Fusion and Power-Shok cartridges standing on a table with hotspots

Both Fusion and Power-Shok are American-made at Federal’s 100-plus-year-old manufacturing facility in Anoka, Minnesota. They feature precision-drawn Federal brass cases, and that consistent brass is the foundation of accurate, reliable performance of both rounds in the field.

Federal primers are the envy of the industry for their extreme consistency and reliable ignition. Both Fusion and Power-Shok are built with them. 

Fusion and Power-Shok are both loaded with high-performance, clean-burning propellant. They’re also tested rigorously and held to tight quality control specifications for pressure, velocity and accuracy.

Power-Shok bullets are what are commonly called cup-and-core projectiles. As that name suggests, they feature a lead core enclosed in a pre-formed copper jacket. The core is inserted into the copper jacket cup, and the two are simply pressed together and pushed through a sizing die to bring the bullets to their desired weight and shape. The construction process is simple and inexpensive, and the resulting bullets are accurate. They tend to expand aggressively on impact—up to twice their original diameter—which is ideal for taking down medium-size, relatively lightly built game like deer and antelope inside a few hundred yards. Power-Shok is also offered in calibers and bullet weights that are up for larger game like elk and bears, but range and shot placement become limiting factors, as heavy bones and tissue can cause fragmentation of the bullet on impact, which can decrease straight-line penetration. 

Fusion bullets are a bit different. Their copper jackets are electrochemically bonded to the lead core. Because the jacket material is applied atom by atom, it creates an extremely consistent jacket, which enhances accuracy. The specialized bonding process also ensures the bullet’s jacket and core remain secured together as it hits and passes through the animal. This translates into deeper penetration over Power-Shok, all things being equal. Also, Fusion bullet nose incorporates a feature called skiving—essentially small cuts in the leading edge of the jacket. These skives help guide expansion for more uniform, predictable and lethal mushrooming on impact. As a result, Fusion is capable of consistently larger game animals at longer distances with much greater consistency and reliability. You’ll pay slightly more for Fusion than Power-Shok, but you’ll get better performance
