  458 HAMR  
458 HAM'R (The 458 SOCOM Magnum)    

The HAM'R is designed from concept to completion to be the hardest hitting, most powerful (practical size) AR platform carbine ever produced, exceeding 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 SOCOM operatiing pressures are 35,000 PSI.


The 458 HAM'R case is longer than the 458 SOCOM case. During 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.


** THE 458 HAM'R AMMUNITION IS LOADED TO MUCH HIGHER PRESSURE THAN THE .458 SOCOM AND IS NOT SAFE TO FIRE IN A .458 SOCOM CHAMBERED RIFLE.
