Just read the thread "Stretching the .44 Magnum Case" on here. Made a lightbulb come on.
Seems as if I read in George Nonte's book, "Cartridge Conversions" that he used a method to lengthen cases by rolling them under pressure with a mandrel. Got to go back and research that soon as I find my book. Seems to me that we should be able to do this to form shot cases for some of the shorter rounds we're tinkering with for shot loads. It would diminish case strength somewhat but most of the shot loads are fairly mild anyway. The .45 ACP and 9mm come to mind.
Any thoughts on this?/beagle
