    Test Rifle: Interarms Mark X, 24" barrel, 7x57

    Chronograph: Chrony @ 10 yards from Muzzle

    Conditions: Cobalt blue skies, 55 deg F, light winds


    Load #1: R&P Brass, WLR Primer, 140 gr Sierra Pro Hunter, 49.4 gr WW 760

    2985 fps :fire:


    Load #2: R&P Brass, WLR Primer, 140 gr Sierra Pro Hunter, 41.7 gr IMR 4895

    2733 fps :scrutiny:


    Load #3: Remington Express Core-Lokt, 140 gr PSPCL

    2845 fps :what:


    Usually, factory stuffed Euro calibers from USA manufacturers falls below the advertised # (2660 fps) so I was stunned to see it chrono and print on target right between the full house and modest hand loads.

    Commercial 8mm ammo is downloaded because there are old mausers out there with .318 bore diameter, as opposed to the standard .323. I am not aware of the same situation with 7mm ammunition.

    If you are loading ammo hotter than factory stuff chronoed, I don't know why you would be mad. It is not hot if it meets SAAMI specs. Did the bolt open with difficulty or was extraction difficult? Did the primer fall out of the brass?

    If you don't see excessive pressure signs I see no reason to be concerned.

    None of the above; just stunned to see Remington Ammo post those kinds of numbers.
