Nosler 9.3mm 250gr Expansion Tip Lead Free (50ct)

The Nosler 9.3mm 250gr Expansion Tip Lead Free (50ct) is a top-tier bullet component designed for handloaders who demand ethical, lead-free performance, deep penetration, and controlled expansion in 9.3 mm (.366″) rifle platforms. Featuring Nosler’s cutting-edge E² Cavity™ (Energy Expansion Cavity™) and solid copper-alloy construction, this 250gr projectile delivers uniform mushrooming and trusted terminal performance without any lead content. Each box contains fifty polished, weight-sorted bullets ready for consistent seating and precision handload development.

Constructed with a .366″ bullet diameter and a tapered Spitzer boat-tail profile, the 9.3mm 250gr Expansion Tip Lead Free optimizes downrange ballistics through a high G1 ballistic coefficient and reduced drag. The E² Cavity™ initiates rapid hydraulic expansion upon impact, producing broad wound channels while retaining approximately 90–95% of its weight. The monolithic copper-alloy design eliminates the possibility of core-jacket separation, ensuring reliable performance through heavy bone and thick hide.

Ideal for cartridges such as 9.3×62mm, 9.3 mm Mauser, and 9.3 mm Magnum wildcats, this bullet excels at delivering accurate impact and ethical terminal results on large and dangerous game. With an overall bullet length near 1.550″, the 9.3mm 250gr Expansion Tip Lead Free stabilizes efficiently in barrels with 1:10″ twist rates or faster, supporting flight consistency and precision in both bolt-action and magazine-fed rifles.

Key technical specifications for the 9.3mm 250gr Expansion Tip Lead Free include a G1 ballistic coefficient of approximately 0.475 and a sectional density (SD) near 0.268. These high performance metrics support excellent downrange energy retention and wind resistance, making it suitable for long-range shots or dense terrain hunts. The solid copper construction also maintains consistent internal pressures, ensuring feeding reliability and accuracy shot after shot.

In real-world hunting scenarios, the 9.3mm 250gr Expansion Tip Lead Free bullet demonstrates fast, controlled expansion, followed by straight-line penetration—ideal for ethically harvesting elk, moose, bear, and other large game. Hunters report clean wound channels, high retained energy, and one-shot knockdowns, even at moderate distances. The aerodynamic boat-tail profile and expansion tip design work together to sustain accuracy and terminal performance in variable field conditions.

This product is strictly a bullet component—not factory-loaded ammunition. Reloaders planning to use the 9.3mm 250gr Expansion Tip Lead Free bullet should consult Nosler’s official load data and established reloading manuals. Recommended powders include Hodgdon Retumbo, IMR 4831, or Reloder 22—all selected for their proven performance with heavy copper-alloy bullets. Proper case preparation, neck tension, seating depth, and maintaining consistent overall cartridge length are vital to ensure safe pressures and accurate groups.

By combining Nosler’s E² Cavity™ expansion engineering, solid copper-alloy precision, and aerodynamic design, the 9.3mm 250gr Expansion Tip Lead Free bullet component offers handloaders a premium solution for large-game hunting—balancing retained energy, terminal consistency, and ethical performance in .366‑caliber rifle applications.
