Premium, Match-Grade Brass for the Serious Reloader

Whether you are chasing a benchrest competition trophy, rolling high-volume pistol ammunition for the range, or developing the perfect, hard-hitting hunting load for the hunting season, your ammunition is only as good as the brass it is built on. Starline Brass is internationally recognised as the gold standard for unprimed reloading casings, offering unmatched consistency, durability, and value for money in this convenient 100-Count pack.

Proudly manufactured in Sedalia, Missouri, Starline cases are drawn from a premium CuZn30 cartridge brass alloy (70% copper and 30% zinc). This specific metallurgical blend, combined with Starline's rigorous vertical drawing process, results in cases with incredibly uniform wall thickness and concentricity. For the handloader, this means highly consistent internal case volumes, resulting in lower standard deviations (SD) over the chronograph and tighter groups on paper.

Unlike cheap, mass-produced factory brass, Starline is engineered to withstand multiple high-pressure firings. The primer pockets remain tight, and the case mouths resist splitting reload after reload. Bottleneck rifle calibres undergo a specialised induction annealing process at the factory, leaving a visible discolouration at the neck and shoulder, a hallmark of premium brass that ensures optimal neck tension and longevity right out of the bag.

• 100-Count Pack: A perfectly sized batch for load development, competition prep, or building a stockpile of your favourite hunting rounds.

• Exceptional Consistency: Rigorous quality control ensures uniform wall thickness, consistent flash hole diameters, and exact internal volumes for match-grade accuracy.

• Extended Case Life: Drawn from premium 70/30 brass alloy designed to handle high-pressure loads and multiple resizing cycles without premature fatigue or primer pocket expansion.

• Factory Annealed (Rifle Brass): Bottleneck rifle cases feature visible factory annealing at the neck and shoulder to ensure perfect bullet seating tension and prevent splitting.

• Broad Calibre Range: Available in an industry-leading variety of calibres, from obsolete and hard-to-find revolver cartridges to modern, high-performance long-range rifle rounds.

• Unprimed and Ready to Prep: Shipped new and unprimed. (Note: As with all bulk brass, it is recommended to size, chamfer, and deburr the case mouths prior to your first loading).
