22WRFM chambering

[Jim Kobe]

I've been tasked with fitting and chambering a barrel in 22wrfm (22 Mag). Client send a 22Rf barrel. I understand there is a difference in the bore diameter of these. Do they make a reamer with the correct pilot size to use the 22rf barrel and chamber to 22wrfm and what are the consequences of doing it?

WRM is.224”, if you got a RF match barrel it is going to be, probably .220”.
The consequences are several and all bad. If he blows up a case that’s a big one.

What about the Ruger Single-Six with two cylinders and only one barrel?

Ruger uses the larger dia. barrel in these revolvers.
