    Default 358 Norma mag

    My 358 Norma mag should be here tomorrow I need a good load I gave 250 hornady spire points and 250 Speer hot-cor. I have h4831,h4350,imr4064,rl15,imr4350 and 7828. Thanks for any help.

    Here is data from Hodgdon #26:

    250gr

    H4350 Min 71.0gr 2634fps Max 75gr 2778fps

    IMR 4350 min 70gr 2598fps max 74gr 2760fps

    IMR4064 min 59gr 2406fps max 63gr 2608fps


    No data shown for RL15, but should be a decent choice as they show H4895 and IMR 3031
    4831 and 7828 likely too slow, data shown for other large magnums but not the .358 Norma...


    Hope you enjoy your rifle!

    PS data shows regular LARGE RIFLE primer, not magnum
    The 4350 powders, Reloader 19, and W760 are the preferred powders

    With the 250 Hornady I am loading 75 grains of IMR 4350 with CCI 250 magnum primers for a velocity of 2700fps. Very accurate load out of my rifle.

    323; i like shooting barnes bullets.....that said my husky .358 shoots barnes 225's @ at nearly 2900 fps w/o excessive pressure. using norma cases and cci 210's with 66.2gr h 4895 my 25" barrel prints 3 shot nearly touching. the 4th and 5th open my group to 1.033.

    best of luck with your fine rifle!
    happy trails.

    That's what's crazy about the 358 h4831 is not the prefered powder. Unlike the the 338 but I do use h4350 in that as well. Been trying to track down some h4895 in the valley. I'm hesitant about barnes im worried they won't shoot well and 45 bucks is a hard pill to swallow for a box bullets. I also figured it is a 358 so why not just shoot 250 out of it, wish I could find some 250 partitions that is my prefered bullet.

    It's been several decades since I parted with my S&L 358 Norma- so long ago that Nosler didn't even make .358 bullets back then. My particular rifle didn't distinguish between Speers and Hornady on paper, but I prefered the way Speer performed on game. No problems with the Hornady, but somehow I had a prejudice for the Speer.

    At the time I had a mountain of the old model surplus 4831. I won't even list the load I used, because that powder is long gone and everything available today is faster burning. I did get terrific accuracy and velocity from it, but both IMR-4350 and H4350 was right there with it. The 4350's just cost more, so I didn't use them beyond some load testing. According to my limited log for that rifle, it was really fond of 74 grains of H4350 and 72 grains of IMR-4350. In spite of the charge difference, velocities were very similar at 2750fps average from the 26" barrel.

    Dandy rifle you got there in a dandy caliber. Once again, I find something to make me really sorry about parting with my old S&L. First time I was sorry was when Nosler started making .358's!!!!!
