Head space comparator gage

[JScott]

rd,  I have read about the method of rolling the cases in a flame using your fingers but instead of using a propane torch you use a candle.  You hold the case halfway between the head and the neck.  When it gets hot enough that you need to drop it, the neck is at the right temperature for annealing.  It leaves some soot on the case neck but it wipes off easily.

I am going to try it using some of my older cases first.
