I just picked up another kibler fowler kit, this time a walnut 20 ga quick ship. I’m gonna be buying a round ball mould for it, what size are yall using? Have any of yall measured your bore diameter?
My smoothbore isn't a Kibler but is a .62 (20 ga). I shoot a .600" lead ball from a Lee mold with a .010" to .012" flannel patch. I also have a Tanner .590" mold.
