In short, your steel must be AR-400 for rimfire* and AR-500 for centerfire at a minimum. No centerfire magnum rounds are permitted to be shot at any steel. No bullets designed to penetrate or containing any amount of steel either in the bullet itself or in the jacket are permitted. More details are in the policy.
*Mild steel is permitted for .22 long rifle, .22 short, and .22 long only. ALL other rimfire rounds require AR-400 at a minimum.
You can have your steel certified anytime there is Range Badge Processing on the AGC Calendar. You just need to bring your certificate showing you passed the test, your receipt from paying the fee, your mounting method, and a sample of the steel you are planning to shoot.
The first step in getting certified is to read the policy and procedures below. After you have read and are comfortable with your understanding of the rules, click on the link for the online test. When you pass the test, you will receive a certificate at the email address you provided. After you have received the certificate, purchase your steel target certification online by making a one-time payment.
When you arrive, the AGC RSO will examine your steel and mounting method and discuss ammunition restrictions with you. Providing everything is in order and you have a clear understanding of the ammunition restrictions, the RSO will send you to the person processing Range Badges and they will issue you your yellow Steel Certification badge and sticker. Then start shooting!
All steel and ammunition used on steel will always be subject to inspection. Steel that is damaged in any way will not be allowed. Surface marks are acceptable, but no pitting, cratering, holes, concave or convex targets will be permitted. This list of descriptive terminology is not all-inclusive.
