Hello Bingo,
I use an old fishing sinker mold for most of my lead balls , it was a very cheap find in a junk shop , it does not cast precision balls , but they are more than good enough for slingshot ammo , (unless you are involved in serious competition).
Bullet molds from Lyman , Lee or RCBS cost a lot of money as they are precision tools.
Hope this helps.
Cheers.
