The printed data says that a sub .45 cal pistol takes 1 grain per caliber, ie, 45 gr. max for .45 cal, .44 max for .44 cal, .36 max for .36 cal.
For the rifles of .50 or so, 1.4 to 1.5 gr. per caliber, .50 equals 70 to 75 grs.
Anything over is wasted powder, gets blown out of the barrel as flash, or melts into the barrel as fouling.
Some don't believe it, but the old way to tell if you were overcharged was to fire over virgin snow, see how much unburnt powder was blown out of the barrel. WHY they won't believe it, since the smokeless people do lay down white paper and check for unburnt powder, is beyond me.
There IS a point of "diminishing returns", where you stuff more powder in the chamber and get less boost than all the boosts before that load. You might get more "kick", but it is because you are blowing more weight out of the barrel, not only the ball, but the powder mass. That does count too, y'know.
I don't know enough about this stuff to tell any of you guys anything. Still, mebbe some is wrong.
