    Default Use of Standard Rifle Primers in Magnums

    Help from Murphy and others. After priming about 33 .358 Norma Magnum cases I double checked and found that I was using CCI-200 standard large rifle primers. I was going to load Nosler Accubond .358" - 225 grain bullets ahead of 74 grains of IMR4350. Since most load books say to use magnum primers, what impact should I expect? Should I dump the CCI-200s and reprime with CCI-250 or other magnum primer?

    Thumbs up Primers

    I have used standard primers in my 338 Win for years.....no problem.

    Try both and see which shoots the best.

    Load 'em and shoot 'em. The CCI-200 will ignite 4350 very well. The velocity will be about 10-20 fps below the magnum primers but will still be a good load. It may be less velocity variations and better accuracy.
    Is there nothing so sacred on this earth that you aren't willing to kill or die for?

    Back when I owned a 358 Norma, it prefered non-mag primers with the old 4831. Never did try 4350 in it, so no direct evidence, but my instinct is that standard would shoot fine, and it would be a question of whether your rifle prefered mag or standard.

    In fact, my son-in-law's 300 Winnie prefers standard with his load of 4350 under a 180 grain bullet.
