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 operating pressures are 35,000 PSI. The 458
HAM'R is basically a 458 SOCOM MAGNUM.
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.
BE SURE YOUR FIREARMS IS MARKED FOR THE CORRECT CALIBER, 458 HAM'R. 458 HAM'R AND 458 SOCOM AMMUNITION IS NOT
