Reamer print/Freebore question

[Gundog64]

All,
When looking at a chamber reamer print, how do you determine the freebore length?

 

[Tozguy]

Freebore is the dimension between the beginning of the bore and the beginning of the rifling.

Freebore 104".

Freebore 104".

Mr. Shuster,
Thank you that is what I thought it was, just wanted to make sure.

Still putting that little metal hanger you gave me to good use. Works best in the pits at Perry but have found a few more places to use it.
