What is the best pokéball to catch Iron Boulder with?

Listed below is a table of the best pokéballs to use for catching Iron Boulder. This is calculated based on Iron Boulder's catch rate, as well as the different possible ball modifiers, health levels, and status condition modifiers. When possible, the conditions required for a particular pokéball modifier are taken into account, but be sure to read the notes below each pokéball to make sure that its bonus applies.

Also, note that for pokémon whose maximum HP is low, the catch probabilities for the Low HP columns might be slightly lower in the actual game than the probabilities displayed here.
