I would move back in to 50 or 100 yards and iron out your process.
Get to shooting consistent, tight groups up closer and then start moving out further.
If there is a problem with your scope/rifle/ammo it'll make itself known at 100.
Your scope has plenty of zoom for 200 yard shots.
There are lots of articles and YouTube videos available on shooting mechanics and fundamentals. They would be worth taking the time to watch
