Looks like your POI is 1 MOA right in both shot groups.Here is my 100yrd zero
If you will look carefully, you'll see that both targets are no longer on a board. They're sitting on a table, and the second target is laying on top on another target sheet (possibly the first one). He removed the targets from the backboard to take pictures of them, I'm sure. But Buzzyb can clarify that himself.Buzzyb's second target shows as tilted right compared to the first target. If it was tilted and he tilted his rifle/scope to align crosshairs to target, then he would induct the type and magnitude of error he got. Seems to me a likely case of a loose nut behind the (rifle) butt!
He set his scope is level….really? Truly level would be parallel to the horizon line on a flat, smooth lake or ocean. I.E. the vertical line would be true straight up. Tilt to the right and see POI shift to the right with all else staying the same.

Your 1 MOA tothe right at 100. So it makes sense you would be 4 MOA to the right at 400Shot this group yesterday 1st pic. Shot same load today after zeroing at 100yds 2nd pic
Read what he stated. The second target he zeroed with 1 shot at 100. The shots to the right of that are 400. Just to clarify the OP.Your 1 MOA tothe right at 100. So it makes sense you would be 4 MOA to the right at 400
Is this a new gun to you? New barrel? Factory gun or custom?Got my gun shooting dead on at 100yds went to 400yds it shoots 4 inches to the right. My scope is level [checked it twice] what could be causing this.
What distance were you zeroed at for the first picture? How many clicks @ 1/4' per click did you adjust your windage for when you then zeroed at 100 yards? Another words what changes did you make between your two groups of 400 yard shots?Shot this group yesterday 1st pic. Shot same load today after zeroing at 100yds 2nd pic
Interesting, but scope canting has a diagonal effect on trajectory. I'd like to know what changes OPer made when he sighted in at 100 yards between his two 400 yard groups.Scope is canted to the right WRT BORE centerline. You can level the gun all you want before installing scope, but in most cases, nothing on the receiver has any positional relationship to the barrel. Put tape on mounts & scope tube, loosen the scope rings, rotate the scope a bit to the left, tighten it down & RE-fire.
