SBR is a veteran-owned business, operating out of southeast Georgia, who started out by providing special purpose and duty ammunition to law enforcement and government entities. In recent years they have expanded their business into the civilian market. Their goal is to produce the best possible ammunition for civilians as well as those in law enforcement and government. All ammunition that SBR manufacturers is thoroughly tested for pressure, velocity, functionality, and accuracy.

The HAM'R is designed from concept to completion to be the hardest hitting, most powerful, practical size AR platform carbine ever produced. The HAM'R exceeds the ballistics of the .450 Bushmaster, .458 SOCOM and .500 Beowulf. By using an AR10 size bolt and barrel extension, this new cartridge is capable of handling maximum pressures of 46,000 PSI while enabling it to exceed 3,000 foot pounds of energy from a short 18" barrel.

The .458 HAM'R case is longer than the .458 SOCOM case and due to normal chambering the HAM'R will not fit in a .458 SOCOM rifle. If you tried to chamber the same HAM'R cartridge repeatedly in a .458 SOCOM, the case shoulder could potentially set back the .040" that would allow chambering, thereby creating an overpressure situation that would most likely damage your .458 SOCOM rifle and potentially cause injury.

NOTE: The .458 HAM'R ammunition is loaded to a much higher pressure than .458 SOCOM. Therefore making .458 HAM'R unsafe to fire in a .458 SOCOM chambered Rifle.
