Just from my experience with Brenneke slugs, some shotguns shoot them well (as in accurately, SxS on the target at good distances, others are not so good.

So before you start you have the luck of the draw.

then add the fact that they are round ball AND that you
are cutting the barrels, I would think that the round balls might not be that accurate.

If all you want to do is make it go bang with a cloud of smoke and throw a lead ball out the other end, it will still do that !!! LOL
