"I'm shooting a 30 Herrett in an AR15."

Yondering,

I've looked at the 30 Herret; Which version are you shooting? Black Hole's, the HRT or AR Performances (which I don't know may be the same as one of the others?)?

Whose dies are you using?

And what kind of velocity (what barrel length & bullet weight)?

Thanks,

Jerry
