Starline Brass Now Offering 300 HAM'R


SEDALIA, MO – Starline Brass has added another caliber, the 300 HAM’R® to the growing lineup of high-quality brass. Starline’s 300 HAM’R® brass is produced with the same demanding quality control standards for which it has been produced for the original cartridge developer, Wilson Combat®, since 2018.  

Originally named the .30-30 AR, the .300 HAM’R® was developed by Bill Wilson in his search for improved terminal performance in the AR-15 platform while still utilizing the standard 5.56 bolt carrier group. The 300 HAM’R® has a substantial velocity and energy advantage over calibers such as the 300 Blackout and 7.63x39 which gives it 30-30 performance out of the AR-15. Bullets in the 110-150 grain range are optimal for the 300 HAM’R® and deliver excellent accuracy. With proper bullet selection you have a firearm with excellent terminal performance in a low recoiling package that hits well above its weight class. This cartridge has been used extensively for hog and deer hunting and has even been used in Africa for plains game.  Hodgdon CFE BLK powder gives excellent velocity and low pressures in this cartridge.

For more information, including 300 HAM’R® load data, barrels, uppers, firearms and reloading dies, please visit Wilson Combat’s website at  HAM’R® is a registered trademark of Wilson Combat®
