When steel first became the law for duck hunting I was afraid to use it in some of my guns because of the choke. That, plus I couldn't hit anything with it.

I had a Stevens 311 police model with 22" barrels and no choke. I tried that gun with steel and began having great luck with it. Close shots and long shots both.

So, I would have to say that steel can be managed with choke restriction...Geo
