Need a tap size for Hornady tool

[donttellthewife]

Does anybody know the thread specifications for the Hornady modified cases.

https://www.hornady.com/shop/?ps_se...&category_id=7df13f42514ab708d0b7ebbd11c32a1b

I have a couple cases I would like to modify to use the with the L-N-L O.A.L. Gauge.

It is a 36 thread pitch and between 1/4 and 5/16, maybe 19/64x36.
I would like to know for sure before ordering one.

Thanks
