Does anyone have a tutorial for figuring out the diameter of three balls or circles or rings nested within a larger circle, if the inside diameter of the larger circle is known?
I know that the traditional OO buck load without shotcup is supposed to use .330" balls. I would like to order a mould that throws the ideal size for use in shotcups. I have heard of #1 and O being used, but is it just trial and error?
I'm a pretty fair hand at trig and geometry, mostly due to my trade, but the circles within circles thing has me stumped. Tried breaking down the configuration into two 30-60-90 triangles, but without one known side, I was stumped. Any suggestions?
