Thread: Viht N550

    Viht N550

    Is this powder(N550) any good for .243? Currently using N160 but its like hens teeth too find. Was wondering if any difference with it having nitrogycerine in. The load chart compares it almost identical to grain weights as N160. Just wondering if you have anymore info.
    Always think before you pull that trigger.

    Its a double base version of N150 which could be a useful powder for medium bullet weights in 243

    being double base it tends to be used as a slower option with longer barrels or bigger cases though

    If you can't get to kelso, I could get some up to you next week mate!

    What weight bullets did you say you were firing?

    N550 is faster than N160, and VV recipes show about 2 grains less.
    It is like IMR-4350.

    I used Vit550 in my 22-250 AI behind 52gr A-max for an easy low pressure 4200fps
