Almost forgot, another member used the 357 Maxi reamer to lengthen his 357 Mag to 360 DW. Said it worked fine and helped the accuracy.
EDIT, don't post before having first cup of coffee. The other member had a 357 Mag that he build as a stub project, the barrel was from either a lever or bolt gun. He ended up with a slightly short chamber that wouldn't accept a 357 MAG, he used the 357 maxi reamer to open up the chamber to 357 MAG. Accuracy did improve over the 38 SPC he was shooting.
Why be difficult, when with a little extra effort you can be impossible?
