There is a danger in using data from older reloading manuals with current powders and components. I have seen data for Bullseye in 12 ga loads in manuals before, but I have always thought that it was too fast burning for my applications. At one time DuPont had data for 700x in several gauges, including 28 ga., but it disappeared in later editions. Speer manual #9 had a load of 10gr. of SR4756 with a 110gr. bullet for the .38 Spl. DuPont didn't even recommend that much 4756 for .357 Mag. and the 10gr. load was not in the Speer #10 manual. What changed? Be careful of the data you use, and compare several sources is my best advice.
