7mm-08 Go Gauge for 7mm-08AI?

[JakeC]

The Go gauge actually becomes the NO GO gauge.....better clarify that. The AI is actually Shorter than the parent case so it would be Go minus .004. I like Minus .006 to minus .010, and on the minus .010 I run new brass through the full length sizer and bump back. New brass will vary a little on the headspace length.

Exactly what I was going to say. PO figured out you can shoot factory accurately without ruining cases if you make the improved chamber shorter. But if you're going to fireform then only reload those cases then it doesn't matter so much. I'd think the smith could zip whatever is necessary off whatever gauge you send him if he wants that.
