Sounds like the problem some of you are having is due to mould cavities being out of round. Mould temp. being off will cause sticking, even with aluminum, bot not THAT bad if the mould was made right to begin with. Take some bullets cast from your mould, and measure the dia. all the way around. If the difference is more than .002" the mould is junk and should be sent back to its maker to be fixed. If enough people did that MAYBE Lee would quit cranking out such abject junk.
