I have been looking for some #12 shot and only found one source and its about $40 for 10# shipped so im thinking of making a shotmaker. I saw it mentioned that the smooth plate that the lead rolls on into the coolant produces better shot the smoother it is. Im wondering if it would be possible to use a piece of plate glass? I dont know if it would crack but i kind of doubt it epically with a the small amount of lead.
