25-06 headspace and freebore

[hemiford]

I need to get a new barrel blank finished. I'm not certain I'm reading the SAAMI spec sheet correctly.
I think I'm fine with a standard SAAMI chamber. I'm not sure yet if I want to handload 25-06
or just use factory ammo.
The freebore is not stated on the diagram, right ?

How much freebore are you folks seeing with various factory ammo in a standard chamber ?

Isn't freebore the same as "back off of the lands" ?

Hmm, it seems you have to click on the attachment to open the diagram

It's not stated you have to do the math:
2.6303 - 2.5253 = .105

Ammo doesn't have freebore. Distance to the lands will be bullet and barrel dependent.
