So I have been casting for a little over a year now and I’ve had great success casting boolits for 44mag(first mold) 357mag/38spec, 500mag, 45LC/acp. Most of my molds are 2 cavity Lee aluminum and I’ve had virtually no problems with them.
From my research, when I get a new mold, I put some neverseize around the sprue bolt, clean the cavities, and smoke it with a bic lighter.
But... I got a new 9mm 4 cavity from NOE, it took FOREVER before the boolits came out without wrinkles. Then, when the mold got hot, everything got extremely tight, after the sprue dries it’s very hard to break the sprue, then, it’s even harder to pull the mold apart to dump boolits. Then once it does open, they seem to cling to the HP pins excessively. I hope I’m doing something wrong or I need to do something different for a HP mold than I do a standard one?
Look forward to any help you experienced casters can give me, I’m at a loss. I thought I had this casting thing figured out
