The .300 HAM'R is a rifle cartridge developed by Bill Wilson of Wilson Combat. It was designed as an improvement over the .300 AAC Blackout cartridge, offering greater range, accuracy, and terminal performance.
The .300 HAM'R cartridge is based on a modified .223 Remington cartridge case, which has been necked up to accept a .308 caliber bullet. It is capable of firing a variety of bullet weights, ranging from 110 to 150 grains, with muzzle velocities up to 2,400 feet per second. The cartridge is designed to offer superior accuracy, high muzzle velocity, and long-range performance, while still providing manageable recoil and excellent terminal ballistics.
The .300 HAM'R cartridge is suitable for hunting medium to large game, such as deer and wild hogs, as well as for tactical applications. It is also popular among long-range shooters and precision rifle competitors, who appreciate its accuracy and ballistics performance.
One of the advantages of the .300 HAM'R over the .300 AAC Blackout cartridge is that it is capable of delivering energy at longer ranges. It is also compatible with standard AR-15 magazines and lower receivers, making it a suitable option for AR-15 rifles.
Overall, the .300 HAM'R is a promising cartridge that offers a compelling combination of performance and versatility. It is a popular choice among hunters, tactical shooters, and long-range enthusiasts.
