Gas Check help needed

[Ballard]

Probably a silly question, but I have to ask it. What is the correct gas check to use on a 311316 mould? Am assuming it would be the .30 caliber. Is it .30, or .32 that is correct?

If they are less than 32 ca (.320") they take 30 cal checks. If they are over 32 cal and under 33 (.330") cal they take a 32 cal check.

thats really not a silly question if you aren't sure.
