    Default additional 30-06 load data...

    I realize the 30-06 has been tested to death over the years but I had good results with a friends well used 1987 tang safety Ruger and thought I would share.

    He provided IMR 4350, Nosler brass and Nosler 165gr Accubonds. I full length re-sized his brass and fully prepped in the tradition manor. I set the seating depth at .050" off the lands for the charge testing, five shot averages are as follows:

    Nosler brass 2.478"
    CCI 200
    Accubond 165gr
    COL 3.305" is .050" off the lands in this rifle.


    54.6gr 2701 fps
    55.3gr 2739 fps
    56.0gr 2777 fps best group, 3/4". Just for reference, ES 17 / SD 9
    56.5gr 2799 fps
    57.0gr 2815 fps
    57.5gr 2839 fps


    I took the charge with the best group results and adjusted the seating depth to .020" off the lands and increased in .025" increments for additional testing.

    Nosler brass 2.478"
    CCI 200
    Accubond 165gr
    IMR 4350 56gr

    3.335" 2810 fps 3/4" group
    3.310" 2805 fps
    3.285" 2771 fps
    3.260" 2763 fps
    3.235" 2784 fps Wide ES and SD, worst group from both testing sessions.


    As the bullet was seated deeper in the case / more jump, the velocity went down with the exception of the last load which was a poor performer. This particular rifle preferred to be .020" off the lands and the 56gr charge was faster at that depth than the original .050" off depth with equal accuracy.

    I suppose a guy could do further testing but this is not a bench grade rifle and the optics were less than premium. I was pleased with the results and he was happy to have a well used hunting rifle capable of shooting 3/4" groups with tuned ammo.

    Final load in the Tang Safety Ruger 30-06 was:

    IMR 4350 56gr
    Nosler Brass 2.478"
    CCI 200
    Nosler Accubond 165gr
    COL 3.335" is .020" off the lands in this rifle.


    Ballistic calculations show 1.8" high at 100 yards is dead on at 200 yards and 7.9" low at 300 yards.

    With a 3" PBR sight in the bullet would hit 2.6" high at 100 yards, 1.8" high at 200 yards, dead on at 237 yards and 5" low at 300 yards.

    I'd be trying H4350 for powder. No secret this is a great recipe for a 30-06. Around 58g, too. Better velocity and probably accuracy, as well.
