Indoor ranges generally will not allow any steel core ammo or any tracer. Steel core ammo can damage the backstop at the range and tracer is a fire hazard. Ranges usually use a magnet to check for steel core ammo as lead and brass are nonferrous and won't attract a magnet. Outdoor ranges may allow both of these, but some regions restrict tracer ammo being fired outdoors because of the fire hazard it presents. The best thing to do is to contact your range before you arrive to find out what, if any, ammo they restrict.
