Fix my gun Excessive bullet twisting/fish tailing?

https://youtube.com/shorts/HGw_3XkSiSI?si=mtGhUtLjJ3sHSpo-

I was trying a new box ammo and put it under the spotter and the twist is fairly significant. That video is the worst of it and after filming other boxes the twist was not as bad. I was wondering if this is something I should be concerned about? The gun is accurate and I was hitting the mark at 600 yards after a few tries.

thanks!

EDIT: the barrel is a 1 in 10” twist rate, bullet is .30 06 Hornady ELD X 178 g

I’m just spitballing here but have you inspected the inside of your barrel? To me it seems if you’re getting the same result across different ammo it may be something in the barrel deforming bullets on the way out? Also if you’re hand loading maybe there’s an issue in the process somewhere.  These are just my thoughts based on what I’m seeing and limited knowledge.
