    Afternoon Pongo,

    Knowing a little bit of the firearms history would be helpful to us as different 7mm norma mag "imp" builders push their reamers different depths.

    The "gunsmith" that built it has a moral obligation to provide at least basic reloading info for its new owner, and if you are not its first owner then that data will/should be on file.

    Its not a chambering for the feint hearted, pressure builds extremely quickly, powder bridging can be an issue with some powder choices as can a few other things

    A rebarrel to 30cal solves a few problems and going 338 solves all of them.

    Are you considering the chambering or have you purchased a rifle in this chambering ?
    A big fast bullet beats a little fast bullet every time
