    If you have access to headspace gauges there is no reason you have to ship the
    action. I would however do it so the gunsmith can check his work and there is no
    question about who did what. Also you will find there are two reamers out there. The
    original 8mm mag case sized reamer, which should clean up the old chamber without
    setting back the barrel, and the "new" (chasing the factory's smaller brass based off
    the 300H&H case ) smaller diameter brass which seems to be the standard now. I have
    read posts that the smaller reamer does need the barrel set back to clean the 7mm
    chamber.

    I am confused. Are you buying a new 7mm mag barrel and wanting it re-chambered? Why not just buy a 7mm stw barrel from Sharp Shooter Supply with headspace gauges and barrel nut wrench and do it yourself? It is very easy and SSS is now carrying Brux cut rifle barrels.

    Well i have all the tools to change the barrel it is just that I found a 7mm Mag barrel and a very good price that makes it worth rechambering i can set the headspace myself but i know some smiths would rather set that themselves i just do not have the capability to rechamber the barrels myself
