I didn't even feel it cut, so don't know if it was a burr at the case mouth or freebore undersize. Wasn't much on the reamer so thinking the former.
I pondered that as well but I don't know anyone with a 450b reamer that I could borrow.
I've "freshened" up a chamber like that once before. It was a 6XC that was cut with an older revision reamer instead of the proper 6XC-II reamer. In that case, I bought a new PTG reamer and split the cost with another fellow who had the same problem. Actually, I paid 1/3 and he paid 2/3 but got to keep the reamer. Worked great.
