Bought this shot maker to try my hand at making my own shot. It's set to make #8. I'm using pure water as my coolant and 85% of the shot is near perfectly round.. some will have a very small dimple. If you change the quality to HD and blow the video up full size you can see the remaining 15% of shot comes out much larger than #8. No big deal as I run it through a sieve and remelt the bad shot.
