I have only seen it once, it does not happen often but it does happen. If you used a standard spec 7mm STW reamer, I would doubt you would have any problem unless you had a very loose 7mm Rem Mag chamber to start with.

I have encountered the same problems with loose chambers and if you don't want to
re barrel then go to a 7mm RUM . It will clean the chamber up and then some.

I like both the 7STW and the 7 RUM so if you want the STW then you will probably have
to rebarrel .

    Don't you have to mess around with a sako extractor and open up the bolt face to go with the rum?

    You can get a Sendero in 7mm Ultra Mag. Why get a 7mm mag and rechamber?

    No !

    The 7 RUM has the same head size as the 7 rem mag, 7 STW and many other Magnum
    rounds .534 case head dia. And no bolt face or extractor work is nessary.

    Remingtion only makes one size long action so loaded COL will be the same unless you
    change to an extended magazine.
