    Chambering: indicate bore before threading and/or before reamer?

    I have read of a few guys that indicate, thread and then indicate again before running in the reamer. I have always indicated once in a 4 jaw then threaded and ran the reamer. Has anyone had a barrel move on them between those steps?

    Yes, the barrel can move.

    Best to indicate, ream, then thread. Its not important that the threads be dead nuts on, but it is important that the chamber be dead nuts true with the bore.

    Indicate several times for an accurate chambering.

    Iím curious too. Iíve heard of guys indicating multiple times, but canít imagine the barrel moving once toques down in the 4 jaw. I use aluminum wire between the jaws and barrel.

    If you don't have confidence in your setup you need a different setup.
