Ok, forgive me for I am new here and to this hobby. I've reloaded but never cast my own bullets.
One of my other hobbies is CNC. Mostly woodworking. Various gun grips and such.
But I've been itching to try my hand at pouring aluminum. How well do you think a lost-wax casting would do for aluminum bullet molds?
I realize there would be alot of trial and error involved to account for shrinkage of the mold as it cooled. But would you get a high enough resolution at normal atmospheric pressure to wind up with a mold that was suitable for lead bullet casting?
