I have 4 or 5 of Jeff's brass moulds, from .595" to .740" round balls - well made and easy casting.

My bro has a set on order right now, for his Joseph Lang 16 bore rifle, mould is .17 bore(.650").

I use Lyman handles on mine as well - or the Saeco handles, whatever is handy at the time. The new Lee handles should also work just fine.
