AR500 steel targets are great for most pistol and rifle rounds, including 9mm, 45ACP, .223, 30-06 308 as well as most other high powered rifle calibers. Steel shooting targets are precision cut with a CNC plasma cutter and submersion water cooled during the cutting process to maintain the integrity of the shooting targets, ensuring the longest life. Warning Shooter and spectators must always wear proper eye and hearing protection. Recommended minimum distances from steel targets to shooter are 15 yards for pistols and 100 yards for rifles. If using non-frangible ammunition use handgun ammunition with a maximum velocity of 1500 feet per second. Rifle ammunition muzzle velocity should not exceed 3,000 feet per second. No shotgun slugs, steel birdshot and buckshot ammunition can be shot at steel targets. Never shoot hardened, steel core or armor piercing ammunition at any steel target.
