hello;
my first bullet mold for cast bullet was a lee single cavity309-190f. no one could answer my questions about casting bullets 40 years ago. Had to learn by trial and error. Got very accurate bullets from this mold but rejection rate was over 50%.
Had fun but bullets from this mold would not remain straight as the bullets cooled. Gave up and got a rcbs mold and problems went away. Still wonder about problem bullets from this mold, they actually got a slight bow in appearanceas they cooled. Suggestions?
Thx
