I've been here for 8 years. That's longer than most convicts spend in prison.

With a short enough barrel and damp enough powder any thing's possible, but normally I'd expect a lot faster. The two tested here (fourth and bottom) managed 1440fps and 1260fps respectively at the muzzle. For most old blackpowder pistols low supersonic is probably a good guess.

As for how much speed is necessary to start doing noticeable harm, here's a look at what it takes to break skin: https://www.ncbi.nlm.nih.gov/pubmed/7175470
Going by that 2J per square centimetre of cross sectional area might be a decent rule of thumb for the minimum necessary to do anything without hitting an eye.

How fast were the black powder loads for 45 Colt?

Just grabbing something off of Google's first page (seems finding more material would be next to trivial to find if you want to look it up in more depth):

>By 1880 they had been surpassed by .45 Colt, .44 WCF (.44-40) and .44 Russian. The .45 Colt was tops. From a 7-1/2-inch barrel a powder charge of 35 grains (civilian loads) would easily push a 250-grain bullet past 900 fps. Military issue loads were a bit milder with 30 grains under the same bullet for about 800 fps.

So for the various six shooters and what not I guess 700fps starts looking more reasonable.

You mean to tell me that Old West loads were hotter than what I can buy today without going +P? Damn, the ammo companies must really be Jewing us down on the gunpowder.

Another reason could be that when you make ammo that people may end up shooting through guns that are well past a century in age, a bit of prudence can keep your legal department from going outright militant on you.

I don't believe that. Buffalo Bore sells nothing but hot loads, and they've never been sued. Even their standard pressure 45 Colt loads start a 255 grain bullet at 1000.

Dam Son, that's pretty slow.
