Are you going to get the Gauges for this?

That would be my only concern as you don't have factory brass non fired as a baseline.

Fully agreed with NSS. Jim is solid on the orders and checks when they ship to him. Shilen has the 30-06 AI.

Frankly I would just go with 30-06, with the powders now there is not much improvement in an AI of that caliber.

On the other hand this is from the guy that is getting a 7.5 Swiss barrel so.......... I understand the interest in something different.

I did a mis set headspace on my 06 Pencil barrel. I had the gauges and somehow still got it wrong and I was being careful. Not by a lot but enough non OEM cases were not all firing. That was with Go and No go, not just the Go.
