You have to remember that the coated bullets start out as Lead bullets and then get coated.

Lead bullets can range from .356 to .358 in Dia and you need to see what will work best in your barrel.......

plus, finding the OAL of the bullet and fps of your load can also
be needed to get the most accuracy from the powders used.

Coated bullet work in a lot of weapons while some don't like them.
Good luck in your quest.
