SBR Ammunition 458 HAM’R 300 Grain Lehigh Xtreme Penetrator Lead-Free 200 round
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. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.
The Xtreme Penetrator (XP) product line features progressive nose geometry to allow for deep, straight penetration while creating a permanent wound cavity diameter exceeding that of most expanding bullets. To top it off, the bullet is solid copper and is able to overcome barriers to penetration; environmentally friendly, target unfriendly, very unfriendly, downright obnoxiously unfriendly. The magic happens with the nose design where the radial flutes force the hydraulic energy inward and then as the energy is restricted, it accelerates outward creating high pressure spikes damaging surrounding tissue. Kind of similar to sticking your thumb over a garden hose. The permanent wound cavity of the XP is from two to four times greater than what a flat or ball nose bullet generates and often larger than traditional expanding bullets. So what you get is exceptional penetration coupled with a larger permanent wound cavity. The solid alloy construction will not deform when contacting hard surfaces like a lead jacketed bullet will do nor will it fragment as some hard cast lead bullets are prone to do. What it will do is overcome surface barriers and penetrate straight and deep while creating a massive wound channel.
Suppressor Safe — The projectile is machined from solid bar stock. This is not a frangible bullet produced from powdered metal.
