I guess it doesn't matter being the TL or regular lube design. Personally I would seat them to fit and function, then start at the low end and workup.
I usually run a few other powders but do have some 231 just haven't opened it up yet.
I usually pull the barrel and use it to fit by doing the plunk test and loading dummy rounds. Once I find where it sits flush with the chamber, I then set the crimp and go to loading.
It's worked well so far with everything from cast SWC's to wide mouth HP's and even the jacketed loads. Till you find what shoots accurate, it's all just an experiment in fun anyway.
