Does a flattened trajectory from velocity increase have more effect on vertical sight adjustment or does increase recoil and subsequent muzzle rise?

What has more effect on POI, muzzle velocity or recoil.

By the time you feel recoil and rise the bullet has left the barrel.

I'll tell you what I know and think (believe?) 'bout that...
By the time the barrel starts to rise, the bullet is already far along its trajectory toward the target.
Bear in mind that everything is relative and that after a certain augmenting of the load, the recoil is too great, and the result is reversed: the recoil is strong, the bullet is too high, and dispersion reappears.
In any case, increasing the load for the same weight of lead influences recoil and POI. You need to find the right compromise between speed and load..

it is all about barrel whip.
Well - it depends.
Firearm weight, grip angle, barrel length, caliber, velocity - all are factors.
neither, as already stated the bullet has long since left the barrel before recoil starts.
However, they will both affect the follow-up shots.

From my own experience, ..., . Not a guess or opinion just real live fire. The rifle begins recoil at the moment the bullet starts moving. Same would apply to any rifle.
Sorry, but I'm going to disagree with that.
If the bullet is no longer in the barrel - what is the firearm recoiling against?
The weight of the bullet upon the first launch, but by that time the bullet is gone.
Here you go, this is a slow-mo of a bullet exiting a barrel as you can see the bullet has left the barrel well before the recoill starts.

andy52, good video.
We agree that the recoil impulse begins at the first moment powder gasses are pushing on the base of the bullet.
What I'm saying is that how much muzzle flip actually occurs depends on the particular firearm.
The vid has a firearm whose design soaks up some of the recoil impulse - a single shot firearm or a firearm with a manually locked breech will not necessarily be able to do what is shown in the video.
I'm going to try and find a slow-motion video to support my view.

The person behind the trigger will have the most effect.
This vid shows a tiny amount of muzzle movement, but movement does start before the bullet leaves.
I'm going to try and find a slow mo video of some muzzleloading examples.

That’s true in Hollywood, after all a Colts dragon will knock a girl over!

Notice too that the recoil motion continues after the bullet leaves but that is momentum because it takes time to slow the movement down. Physics don’t change even for firearms.
If the bullet was gone from the barrel before the weapon moved it wouldn't make any difference how the gun was held. Or even held at all. That isn't the case since different holds cause large impact changes. A loose one hand hold on my 1851 shoots high left compared to a tight two hand grip. If the bullet was gone before the gun moved there would be no difference.
I would think that a semi auto pistol with all its recoil and inertia functions will have a different recoil cycle than a ridged rifle. I don't think what we see in the video is the same as what we would see with a muzzle loading rifle. That's just a theory of course since I can't prove it.

I don't know anything about this but I think that a explosion inside of a container will move the weakest part of the container which in this case is the bullet. as it move a little recoil starts and builds up as the bullet travels down the barrel. when it escapes the barrel recoil is very apparent?
