Seems like I read somewhere about someone using a tumbler and tumbling balls to make them more round/smooth them out. Anyone heard of this or know anything about it?
I have heard of it. Sounds like a waste of time & energy to me, as I have always found the balls I cast to shoot as well as I can hold w/o such nonsense! This is in the same category of rolling cast balls between two plates of ground glass to level down the sprue. Just load them sprue-up. If you have to have pristine, really round balls, buy the swaged Hornady or Speers!
