Starline Brass 10EUP100 Handgun 10mm Auto Unprimed Brass Cases 100 Per Bag

The Starline Brass 10EUP100 is a 100-count bag of new 10mm Auto unprimed pistol brass, produced by Starline Brass - one of the most respected names in American reloading components. These large-format, unprimed brass cases are engineered to fit standard 10mm Auto pistol chambers and are ready for the reloading bench right out of the bag.

Starline Brass cases are known for their consistent case dimensions, uniform wall thickness, and reload-friendly brass that stands up to multiple firing cycles. Each case measures 0.984" to 0.991" in length and is built from quality cartridge brass for reliable resizing, priming, and seating. These cases do not arrive primed, giving the handloader full control over primer selection and load development for 10mm Auto - one of the most powerful .40-caliber handgun cartridges available.

Whether you are handloading for 10mm Auto target practice, hunting, or self-defense, these Starline cases offer a durable, American-made foundation for high-quality handloads. Sold as 100 cases per bag, this is a great choice for high-volume reloaders working with the 10mm Auto cartridge.
