Cherokee My normal pot temp runs 700 to 715 deg. But I haven't liked the weight variation I had been getting. Probably a 4 gr. weight difference. So on a whim I set my pot temp. at 695 to see what I would get for bullets. I had a smaller weight variation but my acseptable bullet weights were still to lg. They ran 2 grains.
I dropped my lead temp. to 685 deg. and my total weight variation decreased dramatically. I had no bullets outside of a 2 grain variation. And my better cast bullets all stayed in a .9 gr. weight variation.
Of the 450 bullets that were cast at 685 deg. the 7 heavy bullets all had fins (from not closing the mold completely), and the 15 light bullets all had incomplete base fillouts. So all of my rejects could have been avoided by my using more attention to what was happening.
Also with the temperature reduction the bullet weight also dropped 2 full grains.
