Bullet marks on paper targets

[D.P.]

After getting home from the range today I was looking over my targets. All shot with a 6.5-284 at 200 yards using 140 A-Max. What caught my attention was all visible (not touching) holes had powder marks along the edge from approx. 12 O'clock to 6 O'clock. The left side of the hole approx. 7 O'clock To 11 O'clock has a clean edge that is peeled back. I there any explanation for this or am I Nuts!!!??? Can a fairly strong cross wind cause this at 200 yards?

maybe your target wasn't at 90 degrees to your muzzle?

Makes sense, targets were on right side of backer. Just never noticed it before.
