    7x57 load

    Hi guys,

    I wonder if any of you can help me out with some load data for a 7x57, I have a ruger no.1 in stutzen version, lovely little rifle 😊

    I want to use a 139gr bullet to start with, so if anyone can be of assistance, your help would be very much appreciated.

    139gr means Hornady then. That little step up to 140gr would open up so many more bullets to you.

    This is a good site i've used in the past.

    It seems nowadays that the 139gr and 140gr labels are interchangeable - often the 139gr in 7mm bullets & ammunition actually weigh 140gr.

    If you've got the Ruger No. 1 International (RSI) - often called 'Mannlicher' - these came in different incarnations with short or standard length barrels. From memory the earlier ones were 22" in a 9.5" twist, and had a short rather than the (usual) long throat. Which length barrel is yours?

    Those I know who own Ruger 7x57s, especially the No.1A, have rifles with pretty long throats, but I would not worry about tuning to that too much.

    What kind of powder do you have?
    H-414 and W-760 ( same powder ) are very good in the 7x57.
    44.0 grains for 2,650 and 48.0 gr for 2,800 fps

    ---- Some Ruger No.1 loads from friends ----------
    145-gr Speer BTSP 46.0 gr IMR-4831 2,625 fps 46,000 CUP 3.065 (inches) 0.75 inch groups
    145-gr Speer BTSP 49.0 gr H-4831 2,719 fps 46,000 CUP

    150-gr Nosler BT
    RL-19 48.0 gr
    3.065 inches COAL
    One ragged hole ( photo ) from a Ruger No. 1A

    140-gr sierra Prohunter or flat base Nosler
    48.0 to 50.0 gr H-4350 ( near MAX )
    Ruger No.1A
    5 holes touching.
    50.0 gr load is 2,750 fpt from 22 inch barrel pressure about 50,000 CUP

    Ruger 77
    Nosler 140-gr Accubond
    50-gr H-4350 or 48.0 gr IMR-4350
    5 shot groups holes touching in a cluster every time. 4 deer at 200 yards or more

    154-gr Hornady
    46.0 gr to 47.0 gr IMR-4350, RL-17, or RL-19
    3.065 inch OAL

    Hornady 139-grain GMX
    Win LR primer
    48.0 grains of Reloader-19 under the GMX produced a velocity of 2,662 fps and sub-MOA groups.
