Thanks Dan. One of these days I'm just going to take the plunge and try some round balls.
My plan was to go with a ball slightly over size, possibly using an unsized case if need be to prevent bulging the case mouth and to reduce the need for belling the case mouth. My thinking is that the slightly oversized ball will provide a bit more bearing surface when it swages down to fit the bore. More bearing surface should keep stripping down and help keep leading to a minimum.
That's my plan anyway.
