A horn carries better especially as a single unit.
Even a loose "day horn" in the pouch carries better.
Smaller horns can be shaped flat.
Cow horns can be made so thin you can see the powder.
Horns don't clang.
Horns don't corrode and eventually stop up.
It's a PITA to prime and load from the same flask.
Many flasks have a valve with a measured charger attached to the spout so the temptation is there to load directly from the flask down the muzzle trusting the "valve".
Both horn and flask carry the the equivalent charge of a WWII grenade.
To me it's easier to get a system or technique in loading from a horn. (uncap-measure-cap-charge-load-uncap-prime-cap-fire) All done with the horn there slung to your side or as a mate to your pouch.
True enough, but there are a lot of references to flasks in the 18th-century literature. My earliest is powder flasks for sale in 1738, Philadelphia.

”¦. Cast sad Irons, Gimblets, Spring Powder Flasks, Brass and Iron Compasses,
I'm having trouble finding it, but I have somewhere a reference to an explosion-proof valve for powder flasks which had been tested and approved. Here is an interesting reference to such a valve, in a comic song sung at Old Hats Pigeon Shooting Club, near London, 1817.
A New Patent Shooting Song
What lots of gun patents, 'tis wondrous I ween
We jolly old knights of the trigger have seen;
Patent pans, patent hammers, and waterproof locks;
Patent breeches and touch-holes, and patent shap'd cocks.
Derry down, down, derry down.
Patent ribs, patent lips, patent barrels, with bore
Of large and small size, for each choice amateur;
With gravity catches, the sportsman's salvation,
And many more articles that mock calculation,
Derry down, etc.
Like a globe patent shot, that in spite of fate must,
When impell'd by the force of Pigou's patent dust,
Go straight to its object with no deviation,
And render death always a sure operation
Derry down, etc.
The
fire-proof flask that the powder contains
Defies all explosion or loss of your brains;
The self-filling shot-bag affords quicker fire--
This principle all shooting men must admire
Derry down, etc.
Overloaded with patents of quackish invention,
A cure for bad shots is their honest intention:
but false to their purpose they greenhorns entrap
And render them worthy--a patent foolscap.
Derry down, etc.
