I just looked at a bunch of ''NEW'' shotgun shell boxes of different makes, every one says on the box,
Do Not Use In Damascus or Twist Steel Barrels, or chambers less than than 2 3/4in. But some of you
guys know better than Remington, Winchester, or Federal and so forth.

Dirty Harry

P.S. They have not made Damascus Barrels in over 110 years or so, but they still put that warning on the
boxes to ''SELL'' Steel Barrel Shotguns Ha HA Ha. Who are you kidding ?
