I use a 12 bore, with steel, for waterfowling. Lots of heavy loads through it, and no problems. Nice to be able to throw it on top of the decoy cart, drag it up the river, without getting too concerned about marring the finish. I (we) also have a 16 and a 28 CZ. The 28 has thousands of rounds through it, sporting clays, with nary a bobble...great value for money....all ours have double triggers...
