I know some of you have this mould as I do. Mine is a 2 hole Ideal and is the hardest to get good bullets with of any mould I own. I pre heat the mould on a hotplate while the lead is melting and run the lead temp up to a little over700*. Sometimes if you hold your mouth just right is starts out dropping good bullets right away and continues through the session. Most times I get a cull rate of almost 50%. The problem is the corners that should be square and sharp are rounded. I like the bullet but this thing is driving me nuts.
