RobS, the mold doesn’t close square is part of the problem. It is open at the bottom, but if I take off the handles, it closes perfectly! By perfectly, I mean square with no gap top or bottom.Like the handles are “ tweaked “ some kind of way. So, before I adjust these handles, which I paid a premium for, I’ll just send it back and have NOE fix it. Ally is ww/2% tin mostly. No thermometer but I run it hotter than my Lee 6 camvity molds for sure.The few boolits I get are wonderful. And it will NOT LET GO of the boolits from the hp pins. I preheat with a hot plate, have polished the pins, hollow point ones that is, cup points work half way ok.im at a loss to put it mildly. When I get it back I’ll let you know how it works, if it does. So, like I said, forward we go. Got other .45 molds that work with no problems and just rain boolits.
