Q:

For all you reloaders: I have been reloading .223 steel casings that I pick up at the range. They've loaded fine, and so far they shoot fine. Recently my reloading mentor of 35 years told me "no, no, you can't reload steel casings". After telling him that I already did, and shot them, he said, "well, you have to be careful, they transmit heat differently, and if you shoot too many in a row, they will start sticking in the chamber and not ejecting". So far, I haven't experienced any problems. Can anyone enlighten me any further?
