That may be a wind issue. The trajectory seem to be the same, but one bullet is hitting a different speed gust from the next....If it's was at all breezy, I wouldn't change anything and wait for a still day to shoot.
Guns usually don't make strings like that unless there is a reason, in your case quite possibly the wind. Or worse yet, your scope mount may be just loose enough to allow for some minor horizontal movement, but not vertical.
Usually groups are more or less circular (at least triangular with three shot groups.) Check your screws and shoot again on a still day.
