Question regarding 25cal rimfire blanks, what case are these based on?

[arakboss]

It appears 22 nail gun blanks are based on 22 rimfire case.

I have read that the 27 cal nail gun blanks share case dimensions with 17 WSM.

What case do the 25 cal nail gun blanks share dimensions with?


Edit: It looks like the 25 Stevens could share case dimensions with the 25 cal nail gun blanks?

I don"t think the 25 blanks match up with 25 Stevens. The 25 cal blanks are not that much larger than a 22 case. If a guy could get a great deal on a big box of 25 cal blanks it might be worth messing around with trying to make them work in a 22lr chamber.

Here are some dimensions on 22, 25 and 27 cal nail gun blanks.

I think the 25 cal blanks could be based off 22WMR case?
