i stand corrected then...
my only personal experience with historic firearms was one shot from a .310 cavalry carbine belonging to a friend. in New Zealand i met a guy who had just picked up a beautiful old shotgun with Damascus barrels from the gunsmith but he told me he wasn't planning to use it as modern firearms produce higher pressure and would damage the barrels.
Ned Kelly's famous armour was bulletproof for the guns of his time but unfortunately that didn't help him, there's a "mythbusters" episode where they show that wild West guns weren't powerful enough to shoot through a hangman's noose --- i still wouldn't want to be on the receiving end of one...
2 of my shotguns are from the late 1800s, both have been reproofed for modern powders, although it is a risk. Blackpowder behaves differently to modern smokeless powders, and needs a very long barrel to extend the range.
I have shot alongside the MLAG (Muzzle Loaders Association of Great Britain) at Bisley, this was out at 1000 yards. Their competition groupings were as good as some of the modern rifle shooters, although the round did take a long time to get to the target.
The Whitworth (1860ish) is often said to be the first long range sniper rifle, targeted kills of high ranking officers were claimed at 800-1000 yards in the American civil war. There are quiet a few similarities between the Whitworth and modern rifles / calibres, including the move to a smaller / faster projectile, high spin rate, thats longer for stability and has boat tail (arguably).
There is some good info on it here.
Southern sharpshooters targeted Yankees with a long-range killer from England. For Union troops besieging Charleston, South Carolina, the summer of 1863

and a good video, with some energy info.
the author has the round delivering 576 ft lb at 1300 yards! I think thats about the same as a 357 magnum at point blank. I think the main issue with a lot of these comparisons is that a blackpowder isn't great in handguns, the barrel is too short, but it can be extremely effective in rifles and carbines.
On the Ned Kelly armour front, some conjecture here that it would stop most modern pistol rounds, and possibly a lot of rifle calibres. But not anything designed to go through body armour.
The first time I wore body armour I didn’t feel particularly safe. There were too many exposed areas where a hot piece of metal could tear into my fleshy bits. Sure, the hodgepodge collection of ceramic plates and kevlar bought from an Iraqi military market were better than nothing, but if...
