Usually looking for PF floors lead data will get you there, 9 major being an exception of course, but I usually don't bother starting at the minimum.
Where coated bullets differ is lubed lead generally maxes out due to velocity causing leading issues, good coatings prevent this from happening until a much higher velocity without gas checks so you can push them faster, of course then you get into an area where you have to watch for pressure because there is no data.
My experience for gamer loads is to just ask, hey I have a coated 135 and X powders what have you guys had luck with for minor? Here I usually get relevent info, elsewhere I often get a bunch of replies about 147s, maybe some 124s, definitely someone going on about something plated or jacketed, a bunch unlisted powders, I then reference the applicable stuff to some published data and as long as nothing screams crazy start there or a couple tenths lower.
