Sounds like you want to win.
Which is perfectly okay.
But, guess what: You won't. Most range visitors are downright "lacking" when it comes to marksmanship in the various shooting disciplines out there. Comparing yourself against them is an exercise in futility, unless you know their shooting background.
Just go, and enter a competition of your choice, and see how you do. Then you'll know. And you'll immediately get a good idea of what you need to practice to become the best (or at least, better than you were last week), and exactly how much work it will take.
