I have a 10ga sxs and at the time when steel came out for water fowl ,the gun was Full on both barrels and then I got in touch with a gun smith about it and he said that the old guns was down value at the time because of the change that use to be goose guns and told him about my and he said bring it down and I did and he looked at it and said he can dix it to shoot steel with out a problem and he put it to IC and told me that I just increase the value of the gun, That gun is good for about 60 yards and I did not lost the distance with it . So you can not blow up the gun like stated but will ruin the barrel if it is not the right choke .
