Can anyone confirm this ADI Headstamp P1 01

[The Raven]

Doing some reloading and discovered a single ADI case stamped P1 01.

Note the P may be an F. If it's F then it matches a ADI 556 headstamp.

Looks to be .223 as it fits my case gauge nicely.

Can anyone confirm?

PS. Primer isn't crimped

In the interest of fucking with your OCD, it is a P01,............................................................................................................................................................................................................................................but may also be a F01 that missed the crimp stage. Happy to help

It's not OCD, I had myself tested over and over again.

Whatever it was, it didn't have a primer crimp and otherwise sized well. But, I'll check it again and again and again just to be sure.

Oh goody, that cleared that up nicely.

Does it have a smaller primer flash hole ??

The flash hole was also smaller than the usual .081.

Suffice to say it’s now mixed in with my other OSA/ADI brass.
