Any modern powder shotgun with fixed chokes should be able to handle Steel Shot. Steel shot does not work the same as lead shot. You need to open up the chokes 2 notches for steel shot!!!! So a Fixed barreled Modified lead choked will become a Full Choke for steel shot, and a skeet lead choke will become a Modified steel choke, a IC lead choke will become a Improved Modified choke for steel. Never use a fixed Improved Modified barrel for lead or a fixed full choke for lead, as you can damage the end of the barrel at the choke with STEEL SHOT!!!!!!!!!
Removeable chokes work the same way----- BUT----- These chokes need to be checked to see if they say lead only anywhere on the tube itself??? Does the choke say its OK for Steel Shot??? Some removeable chokes work for both lead and steel, while others are marked lead only and steel only.
Again Always Confirm with the firearms manufacturer before shooting steel shot in the gun, no matter what kind of chokes you have!!!! break em all. Jeff
With respect, the old rules about opening two chokes to compensate for steel might still apply to larger size hunting steel loads, however in our Club's extensive experience; shooting smaller, slower target steel loads pattern differently.
Having shot millions of steel rounds over the past 15 years, some guns appear to perform better with "real" Full and Improved Modified chokes...
Now, I'm not making any across-the-board representations, but my insight and that of my fellow members come from our results at the patterning board and on the line.
