or:
... The imperfections cause a twisting or turning of the wad as it travels along the barrel and unequal pressure leads to an uneven dispersion of the shot as it leaves the barrel and consequently the mirrored pattern and uneven dispersion on the target.
One way which was proposed to overcome this problem was to provide a new barrel in which straight lands were provided to ensure that the wad travelled down the barrel without twisting. Such a method will prevent the turning of the shot as it leaves the barrel and consequently the mirrored pattern and uneven dispersion on the target.
or even a picture of a gun with one barrel smooth and the other straight rifled, would never make me think that the intention of such system was to prevent barrel fouling.
I guess straight rifling nowadays serves purposes different than those applied in antique weaponry.
Visibly i have been reading the wrong material  .

Ah, Fernando,
There can be more than one right answer to a question. Yours are as right as any others, maybe they ALL are right!.
I am curious as to why other manufacturers did not make more use of straight rifling?
Also maybe there is a way we can date weapons with this feature. When was it first done?
Keeping multiple projectiles more or less together is also a good idea. Note the "Ball and Buck" loads. One ball and three buckshot.
These guys knew how to hurt!
