Ok so I'm pretending that you're an expert in AR platform weapons, combat shotgun, and pistols. Now I'm imagining you struggling with sporting clays for a few weeks, until you master that. Then I will recommend that you work on long range tactical. Lets not make it easy though, set those sights for 1,000 yards. The real challenge is learning to read the wind. And shooting a tight group will not be easy so choose a good bolt action and an inexpensive caliber. You will need lots of practice and time.
You can't fix stupid....however ignorance can be cured through education!
