Vlim, you surprised me!

"Bullet type that can cause more wear to the barrel and that is outlawed on most firing ranges because of the steel core. (mE = Steel jacketed steel core. SE = Sintered Iron bullet)."

A steel core doesn't effect barrel wear at all, and a steel jacket really doesn't hurt it either. The jacket coating material (tombak/GM) contacts the barrel, not bare steel. In addition, SE bullets are solid bullets of soft steel powder pressed together, and there is not steel core per se.
