    Sorry, my bad, Stevens 200 rifle, I don't speak in acronyms.

    Would all MV be throated the same?
    Find your OAL for your rifle. Start at 23.5 and work up.

    Thanks guys, but I'm loading for a Modern Varminter.
    Thought it was obvious when I posted in the ATRS forum,and added MV

    Also,I only asked for Varget load data.

    If you have a MV,you should know this,but.
    The mag col capacity is 2250.

    There's not a great deal that others can share that will be the best choice for your rifle and the combination of components you use.

    I like to leave at least 0.025" under max mag length for reliable loading, and on occasion you might find bullets that touch the rifling at less than max mag length. That's the OAL you'll use in your rifle.

    Then you establish how many grains of Varget are a full case for that OAL, with that bullet, in that case. If compressed loads are safe for the powder you've chosen (and they can be for Varget), I find that I don't like to go much above 105% in the 223, e.g. about one (1 grain). I've often found that even compressed loads fall below published Max Loads with some combinations.

    With a compressed load established, you work up from the published Start Load. Various manufacturers on various days with various bullets and various powder lots will publish a variety of Start Loads, but for Varget, I go to the Hodgdon Site, i.e 24.0 grs for Varget. Regardless of the load I've used, I wouldn't go much above 3000 fps with this combination. That's the most reliable "Pressure Sign".

    Your MV should digest ammo no differently than an AR. No? Most every AR I’ve used varget/SMK in worked well with 23.5-24.5 grains seated at 2.25” oal.
    Work up from 23 grains of varget seating at 2.25” oal.
    Varget is pretty easy - you basically stuff the case and seat a bullet.
    You’ll obviously need to determine how your loads look on paper, note velocities and account for temperatures you’re going to shoot in to ensure it is reliable. While varget’s temp insensitivity claims may smooth velocity spreads in cold and hot temps, shooting hot loads that work great in cool weather may cause your gun to hiccup in warm/hot summer temps.

    You could just load some ammo and figure it out for yourself.

    Thanks,I've never used blc-2,so I wasn't aware.
    Do you crimp? If no cannalure.

    I've tryed both ways without issues , but then you hear all the crap,about setback.

    But I guess it's hard to get setback,when they're compressed
