Boolit Molds an Star Dies

Hi everyone, Hope all had a great Easter.

Need some help with mould an sizer die sizes. How much larger do I want to order my boolit molds over my bore size or chamber sizes in my revolvers? Next, what size do I need to order for the sizer dies (Star). Do I want to order a boolit mold larger then chamber size in order to size it down to the correct size? And if so, how much larger?
For an example; I have a .500S&W, (this is the gun that started me with casting in the first place). Chamber size was .500. Bore size ranged from .500-.501+. I enlarged the chamber size to .502 . Haven't hand lapped the bore as of yet. Leading with this was beyond believe. Hopefully all this work will change this into a fun to shoot an easy to clean gun.
My cast boolits with my low vel. calibers are workin great with TL an Lee sizers. Wish I had done tho years ago as the cast boolits have given me much better groups on paper. Thank Y'all for the help with getting me started.
But before I start with my mag. and rifle casting, I need info on the size question.

503 would be recommended.
502 would work just as well.

it's all an educated guess,,,, till the trigger is pulled.

the more i find out about shootin boolits, the more it contradicts everything i ever learned about shooting jaxketed.

Thank you runfiverun. So I'll order a .503 mold from LBT an a .503 sizing die from Lathesmith. I read the sticky by goodsteel a little bit ago, it helped out a lot with my questions for my .30 rifles, I think, lol. I am so hooked on this casting thing. I don't know anything, but having fun with it.

that's the point, it is to keep right on shooting.
we may or may not save money at some point.
but I know I can shoot and go hunting no matter what everybody else is doing.

it's all an educated guess,,,, till the trigger is pulled.
