    7mm Rem Mag

    For those loading for a 7mm Rem Mag what is your powder of choice ?

    I am using 140g Accubonds and so far Ive tried N165 and am getting neither the required accuracy or velocity.

    Regards

    We used vit 160 when developing loads for my mates 7mm Rem mag, which is a little faster, desired velocities were achieved and more.
    Regardless of what powder you use, the powder has little bearing on accuracy, the bullet being the number one overiding factor in your rifles accuracy.

    have you got a proper 24" or 26" barrel? clearly a slow powder is called for like the 165 you've tried, but it does require a relatively long barrel of course, which the 7RM needs.

    the fact you're not getting enough velocity is surprising, you should be sitting at 3200 to 3300 without too much trouble.

    I am on h4831 until stocks run out but was looking at n165. What charge weights were you using and what velocity did you get

    Vit 560 with 175gr SMK's giving about 0.3MOA groups.

    Give us the facts - what's the load?
    If I'm going to be accused of it then it's just as well I did it.

    Are you getting any pressure signs? The data on the 7mm is often very conservative. You may be able to step the load up a bit
