Brought this topic to the top to inquire once again about the optimal (or typical) load in DDR at the time this gun was manufactured. I am sorely tempted to build some fiber/cork/felt wadded shells with nitro powder. I have the makins, lot of fiberbd. wads, overshot cards, sheet felt left from punching lube wads for C&B revolvers, old roll crimper, but have only used with BP. I have an early Lyman loadbook which may be some help and have seen suggestions internet from those who have used both PB and IMR-7625 in this application but am a bit leery of setting out on my own. Anyone know source of load data for the older components? I have heard that some European (UK?) manufacturers may still be producing these loads for situations/people who desire biodegradable components. Is this the case? Who?
