This appears to be powder of newer manufacture. The cans were unopened and had a date of Jan 92 stamped on them. They came from an estate sale at which I picked up quite a bit of reloading components (mostly a variety of 8 mm bullets. If the data I have been able to find is accurate, the burn rate is close to MRP or N560. It appears that MRP is essentially identical. I have been able to find limited data for R905 powder for loading 7 X 64 with 162 grain bullets and for loading 7 mm RM with 150 grain bullets. I really appreciate all the information you have provided so far. Does QuickLoad have any data for this particular powder?
