I posted earlier in the week about cold weather woes and my first casting session. I got past the problem with your recommendations. I set my mold in the pot with the cold lead and let it heat up with aluminum foil cover the pot. When it was hot enough to flow out of the bottom pour spout, I was ready to go. Did 25 cycles in a two cavity mold. First ones came out frosty. So I let the mold cool a bit. Then got acceptable results for the most part. I rejected half of my sessions bullets due to imperfections. Some got frosty at times, but that alone was not reason for rejection.
Rejection issues...
Lube bands did not line up.
Slag formation where the mold halves meet.
Dropping a hot bullet onto a cool one and deforming the hot bullet. This is an easy fix.
Would appreciate your feedback on the slag and mold halves not lining up. Lee 432-265 from Ranch Dog. Problems not epidemic. More periodic.
PS Dang pot still drips, but I put a catch bowl under it and just recycle.
