Alex,

The barrel would have to be installed by a gunsmith so that he can set the head space to the correct length.
The headspace is the length of the chamber from the bolt face or base of he cartridge to a datum point on the shoulder angle.
This is checked with "GO" and "NO-GO" gauges which resemble cartridge cases without necks. If this headspace is not within the specified limits you can end up with a short chamber, with which you cannot close the bolt on a loaded round, or more dangerous, a long chamber or excessive headspace which can result in a case head seperation upon firing and a destroyed action.
Ian.
