BE CAREFFUL DOING THAT! Pardon the shouting, but mixing hardball and shot shells in the same cylinder can cause big problems when you shoot the hardball first. The plastic cups from the shot shells are not tightly fitted, and will pull forward thru the charge hole, and stop the cylinder from rotating. This is fairly common, and has happened to me twice with Model 60. To get around this, put a very small dab of super glue where the plastic and metal case meet. I carry mixed in the same cylinder, but only after the shot loads are made safe.
