Thread: .358 Norma Data

  1. #1

    Default .358 Norma Data

    I was wondering if any one might have some reloading data for .358 Norma Mag. that they would like to share. I am specifically looking for data on 280 grain A-Frames.

    Thanks

    Thumbs up Load

    That is a very heavy bullet for the 35cal..............today I suggest the 225 TSX or the 250gr Speer GS or Hornady SP or Nosler Part 225/250gr. Even the 225 or 250 AFrame woul be excellent.

    As for load 275/280gr IMR 4895 @ 69 Fed 215 or WLRM primer 2740FPS

    The 358 Norma is basically a 338 Win necked up to 35 cal.

    Bullets weights that perform the best in the 338 Win should be excellent in 358 Norma......225gr and 250gr. I do not have any data for Reloader 15 but it should be a good powder in the 358 Norma.

    I had a M-70 that was customized to a 358 Norma Mag. I still miss that rifle.

    From my log book using that rifle with a 21 inch barrel:

    Speer 250 grain spitzer SP
    New Norma Brass
    CCI-250 primer
    IMR-4350

    79.0 grains = 2,890 fps. Hot winter time load

    78.0 grains= 2,720 fps. very accurate all around load. 2.75 inch group at 300 yards.

    Norma 250 grain Factory ammo from the same rifle= 2,685fps.

    Sierra 225 grain boat-tail with IMR 4350
    79.0 grains = 2,892 fps. Yes, it was not any faster than the 250 grain.

    Barnes 275 grain semi pointed sp. (no longer in production)
    New Norma Brass
    CCI-250 primer
    IMR 4350
    74.0 grains = 2,562 fps. 1.5 inch group at 100 yards.

    I thought I sent this to ya when you got the bullets. Maybe not. Here goes.

    This from a 24" Shilen barreled Sako.

    The 280 grain Swift A-frame, CCI-250 primers, Norma brass.

    H4350 72.0 grains 2575 fps, max load.
    RL-19 74.0 grains 2549 fps, max load.
    RL-15 64.0 grains 2540 fps, max load.
    IMR-4350 70.0 grains 2530 fps, max load.

    I have hit 2600 with this bullet but that is a little hot. I feel better about it at 2550 fps and I don't think the bears will notice.
    Is there nothing so sacred on this earth that you aren't willing to kill or die for?

    Default Thanks

    I appreciate all the responses I received. I do prefer the 250 grainers, but I got a good deal on the 280's so I thought I would give them a try and use them for when I am around the cabin.

    Thanks again and be safe.

    Default too slow for the swift?

    Just wondering if you think this is too slow for the heavy constructed Swift? Wondering if this bullet would be the best for 358 Norma chasing a Kodiak BB.
