What is the best size punch for 30 cal ?

What seems to work the best Punch wise? Want to make up some gas checks for some Lyman 311284 and was hoping someone could suggest a punch size that works for cutting them out of materials. :-?

Don't know. I'd just buy a check maker from Pat Marlin. I ordered 1 in a 35 cal.
