I have always bought reamers as needed, but at 76 years old and getting very arthritic, I'm not going to be doing serious gunsmithing much longer.
So a couple of weeks ago I fell into an early Stevens Model 44 that was not chambered .25-20 Stevens. Bubba had had the barrel professionaly relined and chambered .25-20 WCF. That's the good part, But he then badly botched fitting the barrel to the action. (.020" of excess headspace? No problem.) Setting the barrel back was Job One. Not having any future interest in the WCF cartridge, (even if I were younger) renting a reamer to restore the chamber was justified.
Ordered the reamer from the 4D web site. It was shipped in just under 48 hours, via USPS Priority Mail. Arrived here fresh and sharp, did the job perfectly. Returned it yesterday. Cost was $35 plus shipping. I will happily rent from 4D again if the need arises.

nb: Chambering a Model 44 for the WCF cartridge is a bad idea, generally speaking. Factory WCF ammo is frequently loaded to double the pressure that the old Stevens can stand without "shooting loose". . I of course load my own, so as long as the gun is mine it will be in no danger.
And lucky me! I discovered that I have 100 new Winchester cases! Had thought I had sold them years ago. Indeed they were all boxed up for shipment, but I musta never got a round tuit. Serendipity.
