Bruce I just ordered a pair of roundball molds one at .735” and the other at .775” . The smaller for my tight choked barrels and the other for the pair of factory open choked Parker’s . These molds are brass single cavity without sprue cutters . But it’s quite easy to trim the sprue with a pair of dyke’s (side cutters) .
Www.ballmoulds.com , the pair of molds were about 100 pounds sterling which is about $130 .
