If you don't feel like sacrificing a fine (or perhaps not so fine) double, there is always the option of a classic American repeater. Most are substantial enough to handle inexpensive steel and as long as the chokes as no tighter than modified, you should be fine. Always a good waterfowl option, if nothing else.
That will work on many old repeaters. That being said, John Browning was American--although many of his classic guns were made in Belgium. And Browning recommends no steel through any of the Belgian-made Brownings, including A-5's, Double Autos, etc.
