Product Overview and Introduction

Maximize your rifle’s accuracy and field performance with Nosler Custom Unprimed Rifle Brass in 243 Winchester – Box of 50. Designed specifically to deliver exceptional velocity consistency, flat trajectories, and laser-like precision on varmints, predators, and medium game, Nosler Custom brass provides handloaders with the highest quality foundation for this iconic 6mm cartridge.

Whether you are targeting coyotes across wide-open fields, punching tight cloverleaf groups at the local range, or developing custom hunting loads, Nosler Custom brass ensures reliable feeding, extraction, and extended case life across bolt-action and semi-automatic platforms.

Meticulous Manufacturing and Benchtop-Ready Prep

Nosler treats its custom-line reloading brass as a premium finished component, reducing prep time and eliminating performance variables right out of the box:

• Weight-Sorted and Quality Checked: Cases are meticulously sorted for weight consistency to ensure uniform internal capacities, minimizing velocity spreads (SD/ES) downrange.

• Deburred and Chamfered Necks: Case mouths are deburred, chamfered, and inspected for proper wall concentricity and neck wall uniformity, ensuring smooth bullet seating and consistent neck tension.

• Optimized Alloy Metallurgy: Formulated with robust case heads and properly annealed shoulders to handle standard operating pressures while resisting premature primer pocket expansion.

• Unprimed Boxer Primed Pockets: Supplied clean and unprimed with standard large rifle Boxer primer pockets, allowing you to select your preferred ignition components and powder charges.
