yeah they are sweet, I actually like the fill hole shape on these better than the do its, because with the do it molds I am constantly getting lead squirting upward beside the pour spout and sometimes getting into adjacent fill holes, with these jacobs molds that only happens to me once in a while, in other words I can control any over pour better. the only thing that might get a little tough is when I hold the mold up tight to the pour spout, this makes it a little harder to get the jighead out of the mold because this leaves very little sprue for you to grab with the pliers, so I have been holding the mold up to the spout rather loosely in order to give me a little extra sprue to grab, no sweat then, pretty dog gone smooth heads too, nice and shiney. If I was using better lead and not wheel weight stuff these heads would look like mirrors. ok so I spent a 100 bucks on these 2 molds and they are great, money well spent for sure, I gave some 1/24 heads to a guy yesterday and youda thought I gave hime a million dollars, said he'd never seen 1/24's before.
