    243 gas check measurements?

    I found some 25cal Sierra gas checks at a gun show awhile ago and they are to small. I’m wondering if they are 243 checks miss packaged? The inside of the cup measures.240. The shanks on my two moulds measures .244 and .247. So if someone has a 243cal check I would be interested in knowing what they measure. Thanks

    my 243 gc's measure .233 as the max shank size to fit inside the gc.

    I suspect you have 24 cal gc's.
