I couldn't find this anywhere, and I hope this is in the thw right place.
What temperature is your lead when you pour for boolits and what is the mold made of (brass, steel, aluminum, etc). I ask this question because I use aluminum Lee molds but have picked up a steel RBCS mold. I use a PID controller that is set for 740 degrees for the Lee molds. When pouring into the steel mold I get fins on the nose part of the boolit. I then turned the temperature down to 700 degrees and it gets better. Is the heat still to high oe is it something else.
