Abrasion resistant steel is a high-carbon alloy steel that is produced to resist wear and stress. There are several grades of abrasion resistant steel, including AR200, AR235, AR400, AR450, AR500 and AR600.
Steel targets used in cowboy action shooting A smaller steel target used for airguns. Steel targets are shooting targets made out of hardened (martensitic) steel, and are used in firearm and airgun sports such as silhouette shooting, cowboy action shooting, practical/dynamic shooting, long range shooting and field target, as well as recreational plinking.
In C.I.P. regulated countries every rifle cartridge combo has to be proofed at 125% of this maximum C.I.P. pressure to certify for sale to consumers. [3] This means that .408 Cheyenne Tactical chambered arms in C.I.P. regulated countries are currently (2016) proof tested at 550.00 MPa (79,771 psi) PE piezo pressure.
The Civilian Marksmanship Program (CMP) provides surplus U.S. Army rifles for sale, including the M1 Garand, M1903 and M1903A3 Springfield, M1917 Enfield, M1 Carbine, .22 caliber (surplus and commercial target), and commercial target air rifles to members of affiliated organizations.
Additionally, the Universal Target can be used for rifle or shotgun, while the A3 and A4 paper targets are approved for shotgun matches only. For steel targets, there are two standardized knock down targets, the IPSC Popper (85 cm tall) and the ⅔ scaled-down IPSC Mini Popper (56 cm tall).
It also has a ringmount roof turret, capable of mounting a 12.7mm heavy machine gun, which may be operated from a remote weapon station. Blackwater USA submitted two Grizzly APC vehicles to the U.S. military , with EXO Scale anti- EFP appliqué armor from ARES Systems Group, for the MRAP II competition at the Aberdeen Proving Ground .

Targets for large-bore use are 9.5 to 13 mm (3 ⁄ 8 to 1 ⁄ 2 in) thick hardened steel; small bore targets are 5 to 6 mm (3 ⁄ 16 to 1 ⁄ 4 in) steel, and airgun targets are 3 mm (1 ⁄ 8 in) steel, although some aluminum targets are produced. Ranges are measured in meters only.
MIL-DTL-46177 is an older, now-replaced standard for a high hardness steel RHA. [4] It specifies a harder steel that is nearly identical to AR500 in terms of tensile and yield strength. [5] The Brinell hardness of AR500 is in the 477-534 range. MIL-DTL-46100E specifies a steel of identical hardness. [3]
