Steve, my buddy uses a 311 M/F and for the gunning hereabouts, usually 30-35 yards over tollers, it is tight. I don't know how steel works but probably tighter. Some day I'll get the nerve to quietly open cylinder/cylinder in one of my less-elegant shooters and maybe become a legend, the comeback kid of the century after 65-plus years of scratchy shooting! A legend of this board did that and has trophies to prove it.
