Starline 300 HAM’R bulk brass is engineered for performance and built to meet the demands of modern AR-15 shooters. Developed by Bill Wilson in 2018, this cartridge—originally known as the .30-30 AR—was designed to maximize terminal performance from the AR platform while utilizing a standard 5.56 bolt carrier group. The result is a powerful and efficient cartridge that delivers .30-30 Win ballistics in a compact, low-recoil package suitable for hunting and tactical applications alike.

The 300 HAM’R offers a substantial energy and velocity advantage over cartridges like the .300 Blackout and 7.62x39mm. It performs best with bullets ranging from 110 to 150 grains, and it is capable of excellent accuracy and impressive terminal results. Reloaders using Starline 300 HAM’R brass benefit from precision engineering, consistent case dimensions, and outstanding durability, making this brass a reliable foundation for handloads tailored to both hunting and target shooting.

This cartridge is especially popular for hog and deer hunting in the U.S. due to its ability to deliver deep penetration and controlled expansion. It has even seen success in African plains game hunting, proving its capability across a wide range of environments. When paired with Hodgdon CFE BLK powder, the 300 HAM’R can achieve excellent velocities while maintaining low chamber pressures—ideal for semi-automatic platforms.

As with all Starline products, this brass is manufactured to the highest standards of quality, ensuring reloaders can count on uniformity, longevity, and precision. Whether you’re assembling a batch of match-grade rounds or preparing for your next hunt, Starline 300 HAM’R brass gives you the confidence to push your AR-15’s performance to new levels.
