You have a 17 hmr, I assume.
I would equate shooting a 17 hmr at 200 yards to shooting a 308 win at 1000yards. Wind and trajectory make that a very long shot for a 17.
Practice at 75 yards, long shot at 150 yards. If you want to shoot at 200 work your way out with targets at 25 yard increments to see where it hits, and adjust the scope. (Maybe wait for a no wind day)
You can't fix stupid....however ignorance can be cured through education!
