Jim,
Re. the head("rim") space problem.
If you have a goodly amount of whatever brass lot you would like to use,
you could ask Kirk to chamber/headspace FOR that brass.
Send him several samples of the lot which are at the thickest rims and have him
headspace snugly on those pieces of brass as the headspace "gauges"
Been there done that more than once. It works out well.
