Nosler 243 Cal 6mm 100gr Partition (50ct)

The Nosler 243 Cal 6mm 100gr Partition (50ct) is a premium bullet component engineered for handloaders and hunters seeking deep penetration, exceptional weight retention, and reliable terminal performance. Featuring Nosler’s classic dual-core Partition® design, this 0.243″-diameter, 100 gr projectile delivers reliable expansion in the front core while the rear core maintains structural integrity for deep penetration on medium to large game.

Weighing 100 gr, the bullet achieves a G1 ballistic coefficient of approximately 0.378 and a sectional density of 0.242, contributing to flat trajectories, strong downrange energy retention, and precision grouping in bolt-action and magazine-fed rifles.

Constructed with a flat-base, spitzer profile and a fully tapered copper-alloy jacket, the Nosler 243 Cal 6mm 100gr Partition feeds reliably and performs consistently. Although Nosler does not list a minimum twist rate, handloaders routinely achieve sub-MOA accuracy with barrels of 1‑9″ to 1‑10″ twist—these twist rates provide optimal stability and accuracy for this bullet weight.

Each bullet is manufactured in the USA and meticulously inspected for jacket concentricity, core bonding, and weight uniformity. Packaged in 50-count sealed boxes, this component supports precision reloading and dependable field performance on game including deer, antelope, hogs, and medium predators.

Ideal for ethical hunters, the Nosler 243 Cal 6mm 100gr Partition (50ct) offers a trusted combination of aerodynamic efficiency, weight retention, and proven terminal effectiveness—making it a top-tier choice for serious handloaders and precision hunters.
