I had my barrel chambered from a br smith that used his reamer. I have the ptg reamer print. I want to purchase my own reamer. Now, would the reamer that I get cut the chamber the same? Also, my freebore was cut in a separate operation. What throating tool would I need to manually throat in a separate operation? And how can I match the freebore? Trial and error with a seated bullet in a sized case?
