Nosler Partition Bullets 7Mm .284" 175 Gr Spt 50/Ct

The Nosler Partition Bullets in 7mm .284" 175-grain are the reloader's go-to for building hunting ammunition that reliably puts down medium to large game. Built on over 75 years of field-proven design, the Partition remains the standard against which other hunting bullets are measured—a choice trusted by serious hunters who demand consistent, deep-driving performance across a wide range of impact velocities and game species.

The Partition's design centers on a dual-core construction separated by an internal partition wall. The foremost core is engineered to expand rapidly and violently, creating immediate trauma and shock. That front-end expansion curls the tapered copper-alloy jacket outward uniformly, while the partition wall anchors the rear core, keeping it intact through the wound channel. This means more than two-thirds of the bullet's original weight stays with your shot, driving deep penetration even at extended range or through heavy bone and muscle.

What sets the Partition apart is its predictability. Unlike some premium bullets that perform inconsistently at very low or very high velocities, Nosler's special lead-alloy dual-core delivers superior mushrooming across the velocity spectrum. That matters whether you're launching these downrange from a magnum rifle or a more modest 7mm platform. Each box contains 50 bullets, ready for your reloading bench and your next hunt.

Frequently Asked Questions

What rifle calibers use .284" 175-grain bullets?

The .284" bullet diameter is standard for 7mm rifle cartridges, including the 7mm Remington Magnum, 7mm-08 Remington, .280 Remington, 7x57 Mauser, and other 7mm platforms. Always verify your cartridge specification before reloading.

How does the Nosler Partition perform on large game?

The dual-core design with internal partition delivers controlled expansion and deep penetration, with retention of more than two-thirds of the original bullet weight. This design is purpose-built for hunting applications where reliable, consistent performance through heavy bone and muscle is essential.

Will these bullets perform at long range?

Yes. The Partition's lead-alloy dual-core delivers consistent mushrooming across the velocity spectrum, making it suitable for a wide range of shooting distances and impact velocities typical of 7mm hunting rifles.

What's included in a box?

Each box contains 50 Nosler Partition bullets ready for reloading.
