with black powder and lead/tin boolits, the load data depends on many factors starting and ending with the rifle, and nothing about anyone else's load will or should matter.
my current main rifle load (pedi rolling block) is a 459525m3 523 grain boolit that's gato dip lubed, 66.20 grains of swiss 1-1/2, one .025" milk carton wad, two .002" news wads, ,035" compression (with milk wad), fed 210 primer, thumbed-in boollit (zero neck tension of a fire formed case). but that shouldn't matter much to anyone but my rifle and me.
