I have been told that the steel wares on the old bore barrels. I personally would not use it! I hunted with 1100 back in the days of lead...Lead is softer and less damaging to the steel bore barrels. Call remington...ask them...Im sure that someone there could help you...ask the gun smith in your area.<font face='Comic Sans MS'></font id='Comic Sans MS'><font color=blue></font id=blue>
