What does this mean?

[Savage Armed]

I have a rifle that shoots to the left at 25 yards and to the right at 100 yards.

 

[geetarman]

I think we need more information. I have never seen that occur.

What rifle?

What caliber?

Do you have a scope on it?

Factory or handloads?

I have a .308 that will place 175 gr. bullets slightly left of a similar load with 168 gr. at 100 yards, but have never heard of what you describe.

Need to know what kind of sights on the rifle, and how many groups have you fired at 25- and 100-yards that verify this quirk. The shooting results supporting your statement have to be statistically reliable.

 

[ScottRiqui]

A monster left-to-right crosswind, perhaps?

 

[gizmo688]

You should probably stick to ~60-65yd shots

 

[ClayInTx]

It’s for shooting around corners.

 

[precision_shooter]

Scope/Mounts are off... Recheck and Re-Zero. Replace if needed.

 

[Coyote_Buster700]

Someone Ninja'd your shooting table the instant you shot.

You should probably stick to ~60-65yd shots

Here is what's happening:
As noted above, remount the scope.

 

[Marquezj16]

You have learned the technique of bending

Check your scope and mount.

I believe Mehavey is correct.

However you didn't mention the amount of left/right movement. If it is consistent and very minimal then it could be "gyroscopic drift" (look here). I highly doubt this would be the case at such short distances, but it crossed my mind.
