It was alot easier when the makers provided those recommendations, and the shell makers provided pressure data frown

And at present we have too many powders from multiple countries available for hand loaders. Not to mention the propensity of propellant makers to update any given named canister propellant to significantly change the way it performs over time. But I suppose that keeps the people who publish hand loading data books busy. What edition is Lyman up to now? Last time I looked it was something like the fifty-first edition.

Still, I don’t miss the good-old-days of 1910 :-)
