They don't travel upward. The actually start to drop as soon as they leave the muzzle. The height of the front sight regulates how much of an upward angle the barrel has. Recoil factors in also. A heavier projectile always hits higher than a lighter one with the same load.

"Barrels are bored crooked. Yeah, that's the ticket."

I realize that was probably tounge in cheek but with any open top that may not be that far from the truth. Pie shaped cylinder gaps seem quite common, some point the barrel up, down, left, right or some combination.

Another factor, not my own observation but told to me by a gunsmith, is that how far back the hammer goes determines the location of the rear sight. On Colt's anyways.

But the main thing is probably recoil. All of my guns shoot higher when I shoot offhand vs. firmly planted on a rest. I think modern handguns with taller front sights factor in recoil. Actually the later Colt Single Action Army revolvers seems to have factored in recoil with the .32-20 having a lower front sight than the .45.

Anyways, these are my theories, I'm not formally edjumucated on the subject.

Hi Hewy, BP causes lead to experience anti-gravity. That's the only logical explanation why BP revolvers shoot high?

Or, maybe it's because of recoil?

Understand the sighting in to establish POA at 25yrds or what ever, I was trying to get to  why
the projectiles travel upward, why not down or left/right ? Is it the rifling or distorted shape of a the ball ,
air friction maybe? Barrel length has something to do with it I'm sure. Could be rapid speed reduction after
gas pressure drop when bullet leaves muzzle.

I hope you are talking about 1860 Army pistols. I abhor the Pietta .44 versions of the 1851 Navy.

Original .44's were sighted in at 75 yards so yeah they shoot real high at 25. Modern guns used to use the same sight height and they too shot very high. Pietta and to some extent Uberti have starting using taller sights with Pietta's being ridiculously tall, at least from the standpoint of the originals and do hit closer to POA but they're still high. Navies weren't originally sighted in that far and modern guns for the most part still use the original height but they too shoot a little high but not overly so.

I think that most shooters comment about black powder, replicas at least, seem to
shoot high. A main fix is to install a taller front sight or use the old method of Kentucky windage,
and remember where each one your many guns actual hits.
What I'm thinking here is what causes  black powder guns to shoot high.
Pick just about any gun load the prescribed 30 grs of powder, ram home a.454 ball ,set a cap, aim ...... bang ...............yep high !

Some of it will certainly be used in the smoker. And we have two apple trees to prune this winter.
