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.
As well, the most common material, AR500 steel, or Abrasion Resistant/ Brinell Hardness 500 steel, is actually not created for armour purposes, and thus can suffer major variances in hardness According to Leeco Steel, "While often requested for ammunition target surfaces, AR500 steel plate is not certified for ballistic use". [12]
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.
The projectile has a mass of 370 grains (24.0 g). Claimed penetration of AR500 certified steel is 1 inch (2.54 cm) at 100 yards (91.5 m) and 1/2 inch (1.27 cm) at 775 yards (708.8 m). In 2008 factory loaded .408 CheyTac 420-grain (27.22 g) lead core bullets with 955 copper jackets became available.
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.
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).
An Armalite rifle (AR) is one of a series of rifles the ArmaLite company made or, more generally, a rifle based on one of its designs, such as the ArmaLite AR-15 rifle. Eugene Stoner , Jacques Michault, Melvin Johnson , Robert Fremont, and Jim Sullivan are some of the designers credited with their development. [ 1 ]
The AR-15 rifle usually comes chambered for either the military cartridge 5.56×45mm or the .223 Remington. Because of the pressures associated with the 5.56×45mm, it is not advisable to fire 5.56×45mm rounds in an AR-15 marked as .223 Remington, since this can result in damage to the rifle or injury to the shooter.
