did a quick nothing perty cut away on the mill and this is the HCM case next to it for comparison

Awesome EH! You're the man!
Now which contour barrel is that? The 1.200" diameter shank Sendero or light Sendero contour, or the bigger 1.250" 338 Sendero contour which apparently has fatter SS inner?
And can you roughly measure the SS diameter and the length to the point it starts to taper? Looks like just back from the 2.650" shoulder/neck junction?

that is a 30cal standard sendero contour 1.200" the taper starts 2.675" from face

 

[NZ Longranger]

Perfect! And approx diameter at that point?

 

[Elk Hunter 338]

1.050" it has a step from 1.200 to 1.050" were the carbon butts up against the steel then that length @1.050 is .150 roughly and then its starts the taper

Awesome info EH, exactly what I was after. So will be approx .240" a side of SS left at the body/shoulder junction with our reamer. That will work just fine. We've run a bit less than that with no extraction issues in the past.
Thanks so much for taking the time to do this for me! If ever you're in NZ...
