Federal FB284F4 Fusion 7mm .284 175gr Soft Point Bullets 400ct

The Federal FB284F4 Fusion Component delivers consistent expansion and deep penetration for medium to large game hunting applications. These 175-grain soft point bullets feature Federal's molecularly fused jacket technology that eliminates jacket separation issues common with traditional cup-and-core designs.

What Makes This Different

Fusion bullets utilize an electrochemical bonding process that molecularly fuses the copper jacket to the lead core, creating a single unit rather than two separate components. This eliminates the jacket-core separation that causes inconsistent performance in standard bullets. The skived nose design initiates controlled expansion at velocities as low as 1,600 fps while maintaining structural integrity at magnum velocities exceeding 3,200 fps.

Key Features

• Molecularly fused copper jacket eliminates core separation
• 175-grain weight optimized for 7mm cartridges (.284 diameter)
• Skived nose design for reliable expansion across velocity ranges
• Boat tail base reduces drag and improves ballistic coefficient
• 400 total bullets (100 per box, 4 boxes per case)
• Consistent weight tolerance within ±0.3 grains
• Lead core composition optimized for controlled deformation

These bullets perform reliably in hunting scenarios from 100 to 400 yards, maintaining energy transfer through thick hide and bone. The bonded construction prevents fragmentation on heavy shoulder shots while the soft point nose ensures rapid expansion in the vital zone. Handloaders report consistent accuracy with powder charges ranging from IMR 4350 to H4831, making load development straightforward across different 7mm cartridges.
