CP,
I just got through reading your article in the Rifleman. It got me to wondering about a load I used back in the 1960s. It was based on a 158 grain 3/4 JSWHP I swedged on a Herter's press. I loaded 12½ grains of 2400 into Remington once fired .38 Special wad cutter brass. My Lyman's manual showed it to be a max .38 Special load and a bottom end .357 load.. Now, 40 years later, my manuals show it to be an over the limit .357 load.
Sooo, have they changed the formulation of 2400 that much or has pressure monitoring improved or lawyering caused them to lower the max loads that much?
