Starline Brass

Starline Brass is recognized as one of the premier names in the reloading industry, trusted by shooters and reloaders for its strength, uniformity, and American craftsmanship. Founded in 1976 and based in Sedalia, Missouri, Starline Brass has built a reputation for producing cases that deliver exceptional consistency and long service life across a wide range of calibers. At Arm or Ally, we proudly carry an extensive selection of Starline Brass, offering reloaders components that perform reliably in every application—from competitive shooting and hunting to tactical and recreational use.

Precision Manufacturing and Proven Durability

Every piece of Starline Brass is the product of a meticulous manufacturing process designed to achieve optimal balance between hardness, flexibility, and dimensional accuracy. Advanced heat treatment and rigorous quality control ensure each case maintains proper wall thickness, consistent weight, and precise primer pocket alignment. The result is brass that resizes easily, seals consistently during firing, and endures multiple reloads without deformation. This superior craftsmanship has made Starline a benchmark for reloaders who demand precision and repeatable performance.

Versatile Caliber Selection

Starline Brass is available in an impressive range of calibers that cover virtually every major firearm platform. Popular chamberings include 9mm Luger, .45 ACP, .223 Remington, .308 Winchester, and .300 Blackout, alongside specialty calibers like 6.5 Grendel, 6.5 Creedmoor, and .458 SOCOM. This diversity makes Starline Brass ideal for reloaders who work across multiple disciplines, whether crafting subsonic rifle loads, target-grade pistol cartridges, or precision long-range ammunition. Each batch is polished, uniform, and ready to load, ensuring minimal prep time and maximum reliability.

Performance That Reloaders Rely On

Reloaders choose Starline Brass because it delivers repeatable accuracy and lasting value. The cases are engineered to handle repeated firings while maintaining structural integrity, reducing the risk of premature wear. Their uniform case volume promotes consistent powder burn and precise velocity control, both critical for competitive shooters and precision rifle enthusiasts. Starline Brass is also easy to trim and prime, making it compatible with progressive and single-stage reloading setups alike.
