Just received my 9.3 mold from NOE and happier than a pig in....well, you know. First I give it my standard hot water/ dish soap and a toothbrush treatment. I then gave it a few heat treating cycles in the oven at 300 degrees F. Gave it a dose of brake cleaner outside and wipe it down.
I then warmed it up on a hotplate for a bit, and filled the cavities from my Lee drip-o-matic. I then added bullplate to the top of the mold, and underside of the sprue plate and then wiped it with another Q-tip. All good so far. For the life of me though, I can't get it to drop a nice bullet. They're good from the base to the lube ring, and the rest of the bullet is wrinkley, lines etc.
Now, I'm pretty sure the mold is clean, as this works fine for my other molds, and I think the temp is high enough. I usually crank it for a long time, then turn it down to 6 for casting, which usually works well with other molds. I didn't want to leave the pot on max and risk shortening the life of the mold.
Any thoughts on what my problem is?? Would Bullplate foul the mold and cause what I'm seeing?? What might be my next step. Thanks in advance.
