I think reloading can be one of two things: a complete turnoff or an addiction. It is a lot of work as you said especially if you are really tweaking for the best possible recipe for different components. But the reward can be great. I just sent a photo that I took for a friend at the range today and he found a sweet spot for his Sierra 223 loads today - was putting almost every shot through same hole at 100 yds. He is much more anal about reloading - weighs and separates every bullet, case, etc. But it shows in his results. I mostly reload due to cost savings but have been known to tweak and work on special loads - got a batch of XTP 9mm bullets that I'm itching to start working on.
I have the Dillon 550 but am finding myself performing a lot of steps for 223 separately so I am looking at also getting a turret press or single press for some of that. So I understand why you are doing what you said. Good luck with your experimenting.... one of the reasons why reloading is fun (for me).
