    6.5x55 Sierra 120grn pro hunters and IMR 4064

    Hi I am just wondering if people use the above for a load and what weight of charge they are using.

    Cheers

    BAM! ~Muir

    (The charge weight is only a 3 grain spread between minimum and maximum0

    You're the man How come the OP didn't think of that

    One reason the starting and maximum loads are so close together is:
    - you need a hot enough load with the older rifles to seal the chamber and get good pressure and burning.

    - the max loads are conservative, being for older military rifles.

    I shoot an 1894 Mauser Sporting Rifle in 6.5x55mm and a Ruger M77 MkII.
    37.5 gr IMR 4064 with a Sierra or Speer 120-gr flat base shoots well in both of them.

    I just happened to be loading some 8x60S with 4064, and decided to try it in some 6.5x55 which was up next, and it works. I have not tried to refine it further. IMR-4350 works so well with the lighter bullets, and 4350, 4831 and RL 22 with the 140s and 142s.

    There are so many hunters here in SD who shoot modern 6.5x55 SWE bolt actions that I am sure there are plenty who have proven loads in almost any rifle, bullet and powder.

    My favorite 6.5x55 load with 120's is with IMR7828SSC. Velocities the 2850 fps neighborhood and .3's for accuracy.~Muir

    Yes I had looked on the Hodgdon page earlier. I was just wondering what particular load people used due to the small difference between min and max loads.

    Cheers anyway.

    If you already have the 4064 on hand, go ahead and load up. My 37.5 gr load gets sub MOA groups in both rifles with both the Sierra and Speer 120, and I am shooting an aperture sight on the old 1894 rifle.

    If you can get some 4350, start at 44.0 grains and work up to towards 46.0 and. We just had a thread on this. big ears got about 2,700 fps and 0.5 inch groups from a 20 inch barrel.

    As any .257 Roberts owner can tell you, 120-gr bullets at 2,700 fps will drop deer.
