Supposedly the longer barrel has a longer barrel lag time, the amount of time it takes for the bullet to clear out of the barrel. It's only a fraction of a second, but that represents a longer period of time that the muzzle needs to be held steady after releasing the trigger.
Also, the lock time affects the overall lag time too, having to wait for the hammer or pin to fall or strike, then ignition and bullet exit.
Now a longer barrel is heavier, which is supposed to help keep it steady while aiming and to lessen the muzzle rise, which should help compensate for the extra barrel lag time. But there's always trade-offs and compromises with any gun design.
A heavier gun can cause the arms to be more fatigued which can create more difficulty holding it steady. The trigger pull weight and the length of the stock (length of pull) can also affect holding it steady, and even the LOP is dependent on how many layers of clothing one wears while hunting.
So all of these are factors which helps to either make a particular gun easier or harder to shoot accurately when demanded to during a hunt.
It all comes down to what anyone is most comfortable with when shooting.
Sometimes a short barrel has advantages that the longer barrel can't provide and vice versa.
No one can hold a gun perfectly steady, there's always going to be some movement.
Whenever I advise a new shooter, I try to remind them to exhale 1/2 way and then hold their breath while they squeeze the trigger to help minimize movement.
And then everyone needs to find the most stable way for them to hold the individual gun that they're shooting. Where to place the front hand and the process of squeezing the stock is another variable to work on.
Every shot can be a crap shoot when it's done rapidly in a hunting situation.
The weight of the bullets and the size of the powder charge can affect point of impact too if the additional recoil makes the shooter flinch.
A person might want to compensate by aiming a little bit lower if they know in advance that the muzzle rise can sometimes cause the bullet to impact higher than their point of aim.
