Welcome from another Michigander.
I can't help you with 204 loads, but post a question in the handloading forum and someone will likely jump in and give you a starting point.
Which Lee press did you get? Don't feel like you have to upgrade it, as some of the Lee presses are great.
If some is good and more is better, then too much is just right.
My mind is a raging torrent, flooded with rivulets of thought, cascading into a waterfall of creative alternatives
