Now what to do...

Don
If I may make a suggestion,a chamber cast of the existing chamber & very carefull measurements.
I recently picked up a Pedersoli rolling block barreled action that was sold as a 45/90.
It turned out to be a 45/70 that some one tried to rechamber to 45/90.
There is now a fairly deep ring where the old chamber ended. In this particular chamber the 2.4" reamer did not clean up the old chamber.
The new chamber is cut for gg bullets.
Thnx Lot
