Nosler Partition .30 Cal 170 gr Round Nose Bullets

The Benchmark Hunting Bullet

Since 1948, the Nosler Partition has set the standard for hunting bullet performance. This is the bullet that built Nosler's reputation—a design so effective it remains the choice of serious hunters worldwide.

Design and Construction

The Partition features a fully tapered copper-alloy jacket that ruptures instantly upon impact, curling uniformly outward for controlled expansion. The dual-core lead-alloy construction is the key to its success:

• Front core expands rapidly for quick energy transfer
• Integral partition supports the expanded mushroom and protects the rear core
• Rear core remains largely intact, retaining more than two-thirds of the original bullet weight

Terminal Performance

This design delivers the best of both worlds: rapid expansion for energy transfer combined with deep, reliable penetration. The special lead-alloy formulation ensures superior mushrooming at virtually all impact velocities, making the Partition equally effective whether you're hunting at close range or extending your shots.

The Bottom Line

The Nosler Partition is built for hunters who demand performance they can count on. Whether you're pursuing deer, elk, or other game, this bullet delivers the controlled expansion and penetration that have made it a benchmark for over 65 years.
