Find and buy a copy of Complete Guide to Handloading by Phillip Sharpe. Printed from 1937 to about 1957 with revisions. For the older loads on the antiques, any edition will serve your purpose.

Advice I received from a mentor (now gone) many years ago, who shot all his antique revolvers, especially the .44 Russian Model 3s " Follow Phillip Sharpe and you can never go wrong".

To a newer developments, some of the newer shooters like Clays powder instead of Bullseye to maintain lower head pressures so study the formulas well.
