Originally named the .30-30 AR, the 300 HAM’R® was developed by Bill Wilson in 2018 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 7.63×39 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.
