The Nosler Partition 6mm rifle bullet has been the standard for controlled-expansion hunting performance since 1948. Built for reloaders who demand bullets that deliver reliable penetration and energy transfer across a wide velocity range, these 85-grain .243" spitzer bullets combine engineering proven in the field with consistent manufacturing that makes handloading more predictable. Whether you're preparing rounds for varmint hunting, medium-game applications, or precision rifle work, the Partition's dual-core design and tapered jacket give you the terminal performance characteristics that made Nosler's reputation.
The heart of Partition performance is the internal partition—a steel wall that separates the front and rear lead cores. As the bullet strikes game, the front core mushrooms aggressively to create shock and a wide wound channel, while the partition locks the rear core in place. That design means more than two-thirds of bullet weight stays intact for deep, reliable penetration, even on angled shots or tougher bone. The tapered copper-alloy jacket ruptures instantly at impact but thickens gradually along the shank, controlling mushroom formation whether you're pushing them fast or keeping velocities modest.
Reloaders appreciate the Partition for its consistency. The special lead-alloy dual-core construction and precision ogive design simplify load development and improve shot-to-shot performance. The crimp locks add structural integrity, an important detail when working with magnum pressures. You get 50 bullets per box—a convenient count for developing loads, testing different powders, or building a season's supply.
| Caliber | 6mm |
| Bullet Diameter | .243" |
| Weight | 85 grains |
| Bullet Type | Spitzer (SPT) |
| Base Style | Flat Base |
| Count Per Box | 50 |
The .243" diameter and spitzer profile are designed for 6mm rifle cartridges. Confirm that your specific cartridge (e.g., .243 Winchester, 6mm Creedmoor, etc.) calls for 85-grain bullets at your desired velocity before loading. Always consult current reloading manuals for your exact cartridge and powders.
The internal partition locks the rear lead core in place even as the front core expands. This means the bullet retains over two-thirds of its original weight for deep penetration through heavy bone and muscle, while still creating a wide, damaging wound channel. That combination of shock and penetration is why Partition bullets have remained popular since 1948.
The Partition line is built for magnum velocities. The tapered jacket and crimp locks are engineered to handle the pressures and velocities of magnum rounds. Consult your reloading data to confirm the correct load for your specific magnum cartridge and powder combination.
This box contains 50 bullets, a practical quantity for load development, testing, or building a full season's worth of rounds.
