I have a six cavity mould that I was sure was casting off center boolits. I thought I had tried everything to make them size square, so I called Lee and Andy(tech) told me to send it in and he would check it out. He called and said it was "in spec", only .001 out of round and centered with the parting line. I asked about the sample boolits I sent that were clearly sized more on one side than the other. He said that he didn't know but the mould cast in spec. He didn't think I was lubing mould, but I explained that I used Bullplate, which I find to be superior to beeswax. He offered to send a new mould at cost, but as I had already bought a replacement, I declined. After getting it back I examined the mould under magnification and found that in trimming out the bevel base, I had left metal standing proud on one half of the mould. I trimmed this and cast with it, the boolits looked better on the bases. I then went through my nose punches and selected one that would center the boolit nose well even though it made a ring on the nose. Evenly sized on all sides. My humble apologies to Lee for all those dark thoughts. Wish you would make the boolit designs without the bevel base, which I find to be useless and an annoyance.
