Well I finally bit the bullet and purchased a Lee 6 cavity mould in .357 158gr r/f. I have read so many threads here about the weak sprue plate cam and how they are prone to breakage, this has stopped me from trying one of these moulds till now. I have to say I am so happy with this mould and how it performs, no real hang ups just open the mould and they drop out as sweet as. I have to say I can not see how one could break these sprue cams unless you let the lead harden over night and beat the living …. out of it. I will be replacing a few of my double cavity in the future, I am one happy camper. Regards Stephen
