Thread: Rechambering question for you experienced machinists

As this is a metaphorical/theoretical exercise in wildcatting, SAAMI specs would not apply. Obvious parameters such as pressure and headspace are a given though.
This was more directed at the area of the chamber were new reamer dimensions may be very close to or the same as the existing chamber, such as around the case head. But gundoc quite rightly pointed out the obvious regarding barrel setback, and that would give the re-chambering job some metal to shave off and clean the new chamber. I was aware of barrel setback being a common practice, but didn't connect the dots there.

In my theoretical exercise I am designing a wildcat with a longer chamber than the existing one, so headspace is not an issue, new brass would be created for the new chamber.
