I would surmise the OP is making reference to: bimetal bullets not, steel core! "Bimetal" is often confused with "steel core".
The bullets are lead-cored, but steel jacketed, with a very thin copper coating over the steel. So, the term bimetal refers only to the jacket and not the bullet as a whole. Many indoor ranges prohibit their use because they spark when thet hit the concrete backstop. This could ignite unburned powder and cause a fire!
