Glad that someone with more experience than me can confirm my limited observations. That's why I want to make the pushrods fit the die as closely as possible. It also "means that if you have some weird size die for your .43 Spanish or something" you can be assured that you will get a pushrod that fits and doesn't just barely work.
30 cal.*5shot - No reason to upgrade at all. The die holder is just a much simplified version of the Mark I. I couldn't afford to make the original version, too much machining and hand work.
*Missionary - got your PM, will respond shortly.
*cherokeebill - you get a third caliber, what would you like?
