Couldn't a brass/aluminum mould be recut from a smaller diameter RB mould? How about Dixie's blank 'scissor' type mould of mild steel? I used to have one but sold it, I wish I had kept it to be buried with, so I could avoid bullet shortages in the hereafter, LOL!How about the brass two piece mold made to order to whatever dimension of ball you like. Set up to work with Lee loaded handles. Saves a lot of problems with casting. You could make a mold from aluminum on a drill press I suspect.
That's why engineers are so valued. Can you imagine having to do all calculations on a slide rule instead of a computer? I worked in a soils laboratory in the late '70s in which the results were achieved on an 11 decimal place calculator.Wow Zonie I feel like Gilligan listening to the Professor after reading that explanation! lol
You guys are awesome, what a wealth of knowledge here

That's a good start but unless you have quite a bit of machining experience and the right machines you'd better have some extra aluminum to practice with. I didn't have either the experience or really good machines but I still managed to make a mold that cast a fairly good bullet. The two problems I encountered were getting the cavities exactly halfway into each block so that the bullet wouldn't hang up and allowing for the thread lash in the equipment which gets things out of alignment. I'd also not expect a $15 Chinese endmill to be truly round or to run without any wobble. In that case you will be doomed from the start.Another option is a $15 made in China 12.5mm (.490) ball nose mill bit and 2pcs of aluminum.
Before I retired as a tool and die maker/tool grinder I made some .440 and .490 ball end mills which I used to make molds from aluminum blocks plus I made some mini molds on my lathe. A lot of time but worth the effort for the satisfaction of making my own molds.Another option is a $15 made in China 12.5mm (.490) ball nose mill bit and 2pcs of aluminum.
