That’s not exactly right.I will try to explain cant quickly. Using extremes.
The bullet leaves the barrel 1.5”-2.75” under your scope. Most rifles are set up between 1.75-2.25”. That is significant. We are not shooting laser beams. We are shooting a bullet that leaves the rifle and immediately pulled by gravity in an arch until it stops.
If you took your rifle and laid it on its side with a 90 degree cant and dialed 8.4mil on your scope for a 1000yd target. Would you expect to hit your target? Absolutely not. Even if you had perfect fundamentals and great npa you will miss your target by a lot.
Well now break the same shot with a 45deg cant…you will still miss by a ton. Now try 15deg cant. Still missing. As you get closer to 0deg can’t you will start seeing less drift on your POI.
This is just basic physics.
Wind would affect the bullet the same regardless of the roll of the rifle. And your windage changes on scope would do the exact same thing as long as your scope is level to the ground.What about windage?
That was a point I was going to make...er...ask; if you take a barreled action and clamped to a table and fired it, then rotated it 90 degrees, then rotated...the bullet will perform exactly the same. It won't land in the same spot of course, that's why we zero the optic. based on the orientation of the action bedded in the stock and fired from our shoulder.That’s not exactly right.
Many mount a red dot or second optic on 45 or 90 offset from gun being up right. Doesn’t matter at all.
If you laid your gun on its side, and mounted th me scope at 90 degrees, then the bullet would still behave with regards to gravity, not the orientation of the gun to the ground. Think of a gangster turning pistol to the side as he shoots.
I’m not saying it’s the best way to do it. But as long as the reticle is plumb with regards to up and down then the bullet will behave the same when it leaves the barrel.
If you were shooting at a target that was the same range as your zero that is correct.That’s not exactly right.

See this picture. Special forces offset optics all the time. The bullet is still shooting straight and dropping towards the earth curve.

I am talking about windage adjustments for long range to compensate for the cant of the reticle. Short range the difference is immaterial which is why it doesnt matter for combat. Most of the time the offset optic is a red dot with a short range zero. I even have an offset red dot on my bolt coyote gun for close shots.Wind would affect the bullet the same regardless of the roll of the rifle.

I think this would be the easiest way to show what's actually going onSome body mock up a model with an arrow shaft and a rod tip then close this thread.
Not disagreeing with any of that.A lot of yall are either conflating multiple things, or confused about what is being discussed.
Offset dots are rotated so that the bore is directly under the dot.
That is not what is happening when you have a reticle level to the earth, but canted to the rifle.
In any case, unless extremely canted to the rifle, the effect on windage and elevation is minimal and hard to detect. However, it still is a sub par method for the reasons that I outlined.
15 degree cant with 2.25 inch scope heightI will try to explain cant quickly. Using extremes.

It’s the year of our Lord two thousand and twenty four. Please tell me you don’t think a bullet rises when it is fired from a barrel.Because the scope and the barrel are no longer on the same plane and a bullet still rises when it is fired from a barrel regardless of how much it is canted.
Well, if the barrel is canted upwards......It’s the year of our Lord two thousand and twenty four. Please tell me you don’t think a bullet rises when it is fired from a barrel.
Even canted upwards, gravity takes over the second it leaves the barrel and it starts dropping from the line of the bore.Well, if the barrel is canted upwards......
But I had the same thought when I read that.
What if it is canted to be parallel to earths gravitational force..... Would the gravity from the sun or the moon be more significant or would both be insignificant compared to earths rotation? Sorry.Even canted upwards, gravity takes over the second it leaves the barrel and it starts dropping from the line of the bore.
(I know you know this but I had to say it for others.)
