I guess you would have to define tinkering. To me long seating a bullet so you can put more of a slow for caliber powder in a rifle case is tinkering. If I was doing that I'd be using quickload and comparing it against a chronograph. OTOH loading XTPs into my 45 using load data meant for a Gold Dot is not tinkering in my mind. The most adventurous thing I do is reduced rifle loads using Green Dot and 2400. I don't need quickload for that.
New gun, same ol' shot.
