Call me cocky if you want, I really don't care. I shoot weekly so maybe that's why, but I've mastered several of my guns and am extremely adequate with them all. Practice in general makes perfect.
That's a bold statement. I bet if you asked someone who shot over 100k rounds a month if they completely mastered their weapon system they would tell you that there is always room for improvement. I've never met a perfect shooter until now, I have to say I'm impressed.
