GNOAHHH said, "Ditto on your observations re: 4759. If that stuff were still available all discussions regarding reduced '06 loads would begin and end right there. I too have a pretty significant stash of the stuff for '06, .30-40, and .30-30 reduced loadings (mainly with cast bullets though) - not as much as you, but close."
Dunno if you've taken a look at 5744. I've done a little work with it and the 220 gr. Lyman #311284. Just a few day at a load in the middle of the Data in the Lyman Manual # 50. Rifle was a Browning B78 in the good old 30-06. You might want to take a look at that for some milder 06 loads. Accuracy was decent for a first go at using that powder. Only have one can of #4759 so I'm saving it for later use.
