I can give you two options.
If you want to use one size for all those revolvers, order a .432 diameter and size in a .432 die, but tell me you want to use these large bullets in many revolvers and I'll make the forward driving band short so it will chamber in any gun. - You'll give up a little accuracy with this method, but not a lot and it gives no complications.
Best is to measure the cylinder throats of all your guns and fit bullets to each individually. Preferably lap the barrels too, using the LBT lap kit. (One kit will do them all.) If you do this you'll do well with a .432 mold, sizing the bullets down to as small as 429 if need be. .003 sizing won't effect accuracy. If you happen to have a gun or two with throats larger than .433, try the 432 bullets and if they shoot well enough to make you happy, be happy. If not, get another mold in a larger diameter as needed.
Ross Seyfried once said. (In essense.) Don't fret too much about selecting the perfect mold from LBT. If you take the poorest one for your needs and size it to nominal size it will probably outperform any other cast bullet available. Sizing to fit the gun does give optimum accuracy.
