I remember now the name of the place that rents reamers. They are called 4D gunsmithing supplies and they rent out Reamers and other gunsmithing tools that a 'smith would only need from time to time.
A number of years ago I rented a 300WBY reamer and a T-handle for it and re did a Browning A-Bolt chamber from 300 WinMag to 300WBY Magnum which turned out wonderful. Beginners luck I am sure but with care and lots of cutting oil it can be done and they will help you by renting you the tools to try it yourself if you want to. If you mess it up, you have only screwed up a factory Model 700 barrel and those plus aftermarket specimens are easy to come by.
Best of luck whichever way you go.
LOVE God, LOVE your family, LOVE your country, LIKE guns and sports.
