For the last 20 or so years i use bullet lube that oozes out around my sizer dies . My old lyman sizer is about worn out.
If i am alloying specific mixes i use a small amount of soldering flux. Seems to work well.have a half dozen muffin cup disks of bees wax also that if its handy i will shave a curl off and drop in a pot that is really dirty ,like old lead sewer pipe.

the consolidation of the states into one vast republic, sure to be aggressive abroad and despotic at home, will be the certain precursor of that ruin which has overwhelmed all those that have preceded. Robert E Lee
