This is a great thread...thanks for starting it! Just getting into loading for .44-40 as I have a Navy Arms Winchester '66, I've loaded up 50 rounds of 200gr bullets over 7gr of Unique but have only managed to shoot off about 10 rounds so the jury's still out. Looking forward to brewing up some BP rounds with the same bullet and also chrono'ing both. Need to keep pressures low due to the brass receiver.
