Reason I was wondering is because if you can make your own bird shot it would knock down costs then instead of loading 1 1/8oz only load 1oz or 7/8oz. That way you are reducing your powder and also shot you use. I have been reading about it for 3 gun and also my buddy shoots clays a lot. So we were both thinking about going in on a MEC600 jr and then maybe making our own shot. So your costs are really just wads, primers and powder.
