That's what I thought until he mentioned it coming back to center at 1000Perhaps the action or scope are canted. Check the scope with accurate levels. I've also seen bedded rifles with the action canted in the stock.

If you reposition for the different distances my money is on your trigger-pull. If you shoot with either hand the rifle usually/often pulls off to one side or the other for many people.I thinks it's mechanics, not physics
+1, I'm guessing head positioning.Video yourself, play back slowly and pay close attention. Of course take all the mechanical out first! Is your caliber a heavy recoiling round? If so pay attention to video, yourself and rifle reaction!
I have been following this with interest because it appears that you know what you are doing, the comments are on point, and the problem appears to be repeatable. It would seem that, unless you are really changing your hold, the problem would be the scope. I have not done a lot of long range work. Mine has been limited to about 600 yds and the single thing that allowed me the most improvement was shooting paper at that range. I would like to suggest that you shoot a tall target with a single high aiming point on a windless day without using any scope correction for elevation or windage to rule out some weird scope malfunction. Or, if the "walking" error is large enough that you could see results at 100 or 200 yds, you could shoot that single range with groups that are corrected for elevation at the various ranges you identified and see if the scope is walking the rounds laterally. Additionally, you could shoot a single range target with windage corrections for the various distances and see if the scope is consistent in applying the correction. ....... despite what I said about following this closely, I just realized that you had reported this as occurring with several rifles. I suppose my methodology could be used to rule out interactive windage problems on the range or computational errors in the ballistics program at a fixed range.This has been driving me nuts. I do a lot of load work up for various cartridges and rifles and everything I shoot starts to walk over to the left from where my Kessler or Hornady app tells me it should out to about 800 yards and then comes back to center about 1000. Wth? I've ordered a couple of those scope levels to try but I'm not feeling confident. It varies with different cartridges and is usually about 2-6" at 600 yards. It's definitely repeatable and I usually just aim to the right a little. Bergers and Hornady and hammers, don't matter. What am I doing wrong?
I agree. Without the bubble you may be canting a little to left also check your trigger pull with a MantisX to see if you are pulling to the right a little and then spin drift at distance is bringing you back to the right?also curious i have seen this before i think its due to the spin of the bullet
As far as shots stringing left I'd guess it's something with the mechanics of your shooting. Maybe something with recoil management or trigger pull etc.though I'd lean more toward it being in head position and cheek weld. Would also look at spending more time adjusting parallax to be sure you're where you need to be. Is there consistency so the stringing I.e. first shot good then the rest wander? Maybe barrel heat is effecting your sight picture? The likely reason for the bullets correcting to the right the farther out you go is simple spin drift and some coriolis effect.This has been driving me nuts.
