I found this while searching for blackpowder ballistics. The chart not only has blackpowder ballistics, it has smokeless ballistics, for both common factory loads AND reloads. It also has some musket and rifle ballistics in both smokepole and smokeless categories.
The author seems to be an all-around gun guru. He teaches all manner of firearms-related skill sets, and maybe even some edged-weapon stuff.
Too bad he is out in PA or I would drop by and chat him up.
