I had been wanting to make a mould for lead balls ammo for a long time. I made a first attempt with a piece of aluminum for 6mm lead balls but it didn't work very well. however, I understood my mistake and with another (larger, flatter, more parallel) piece of aluminum I made a good mold for 8mm and 10mm lead balls. now I can quickly cast all the ammo for the slingshot I want!

Here below I attach the link to the mould machining/construction video and first castings of first lead balls.

 
I have found if you're using lead, 40 cal is about the right size and weight with these modern slingshots.
 
yes, I agree with you. .40" is 10mm. if I want some more fps and less power I use 8mm that is .32"
