    I have a new unchambered stainless Number 4 profile Pac-Nor barrel in the shed that is 28" long. It is in .338 Calibre.

    Is this barrel suitable for a .338 RUM?

    If so what would be the recomended finished length after chambering and cutting the barrel crown?

    Thanks............

    yes a 4 is fine.
    your finished blank will be 26 to 27 max after removing enough on the muzzle end for the lapping wash-out.

    Thanks Coyboy,
    It should make a good all round rifle with a bit of LR ability as well.
