I finally got around to casting with my new MP 452 and 434 brass molds. It took me quite a while to get the rhythm and temperature dialed in. MUCH different casting experience compared to steel and aluminum molds. Had to run the pot at 745 for the 452's and 725 for the 434's. 20 degrees hotter than I do for my RCBS molds. My hands were wet and dirty, the boolits are actually nice and clean.
