The .458 HAM'R (11.6x39mmRB) is a large bore, centerfire rifle cartridge, designed for use in AR-15 style rifles. Wilson Combat, owned by Bill Wilson (developer of .458 HAM'R), sells a .458 HAM'R chambered, AR-style firearm named the WC-12, which is between the sizes of the AR-10 and AR-15 platforms. AR-10 platforms with lowers that accept an AR-15 cartridge can also safely fire the .458 HAM'R. [1][2][3]
It is very similar to the .458 SOCOM, specialized to operate at higher pressure, offering an increased range in a flatter trajectory. The cartridge uses an AR-15 sized magazine, but the cartridge pressures require a bolt, barrel, and receiver designed for the pressure of the AR-10 platform. [1][2][3]
Designer
[edit]Bill Wilson of Wilson Combat designed the cartridge.[1][3] The .458 HAM'R has a single sister cartridge under the HAM'R name, the .300 HAM'R, also designed by Wilson Combat.[4]
