I been using only lee molds since I started casting. I was casting with the lee 358-158 double (going to load for 350 legend). New mold, could not figure out why the spur plate would not cut, could not get a good drop out. Gave it one more try before another cleaning. Ended up getting the mold smoking . Never had a pistol or rifle mold like to be that hot. I have had round ball, mini ball, and reals like the mold that hot. When I was done, pan full of boolets. Was such a good session my lee bottom pour was not dripping
