Well I decided to give this brass mold a try. Lord almighty was it wrinkled boolits for DAYS. I remembered reading 2 things, these brass molds like to be HOT and to give myself some time before cutting the spur plate so to rotate between each molds. Well this turned out to be counteractive. This gave the MP mold too much time to cool down. So at some point I put down the old 358429 and started banging away at the MP mold quickly and then the boolits started looking good. Below is the best version of each I think but most of the ones I kept are of this quality. One thing that stuck out was the deep cavity pin, one would stick badly. I did the old lead pencil trick and it worked for a while. What I ended up doing was lightly taking a pair of scissors and getting in the lube groove and pulling it out like a tooth. Worked decent and was quick. I'm in absolute love with the Lyman 358429 mold though.
If I had could do anything differently I would rather have the 2 cavity instead of 4.
