As stated I have not shot cast in Semi-autos though it was all I shot when I was shooting revolvers.
As I have not and do not shoot cast I have not slugged either barrel to determine size though I know that normally a .001/.002" oversize is used with cast bullets. And with some 9mm barrels people are going as high as .358/.359"
With the Witness barrel with a .452" plated bullet if they are not sized and crimped perfectly I have all sorts of feed and cycling problems. So I couldn't begin to imagine and oversized cast lead bullet trying to be but in this gun. On the other hand the XD is much looser and I don't think there would be a problem. So for now I am sticking with plated.
