    Rifle is a 16in barrel Tikka.
    At 66mm chambering a round in my rifle is still swaging rifling marks in the bullet however I shortened it up so it is still easy to chamber. Interested in what OAL everyone is using?
    Is anyone using any fillers or having issues with inconsistent velocity?
    Stop drilling out flash holes and there is no need for Magnum primers you are not tried to ignite coal, If standard primers will ignite 46.00 grains of 2206H why won't they
    work with Trail Boss that is even easier to ignite,
    Give your barrel a good clean any copper in there will cause lead fouling, the 11" twist will stabilise the 200 Grain but try the 151HP that works in any .30 cal.

    ...and don't use fillers with Trail Boss as it's not position sensitive. Does not have to be stuffed back up against the primer hole.

    Half the harm that is done in this world is due to people who want to feel important. They don't mean to do harm-- but the harm does not interest them. Or they do not see it, or they justify it because they are absorbed in the endless struggle to think well of themselves.

    They might be made for the military (the bullet although open tip is not designed to mushroom so "legal") and also sold to civilians who want to be very civil at the range -- maybe also sipping tea from a cup and saucer at the shooting bench while the barrel cools in between.

    Someone somewhere will do a water jug experiment before and after annealing the tip, but I doubt it will do quite as well as HP soft lead boolits.

    Yes, it looks like this ammo uses Open Tip Match (OTM) projectiles and I'd be curious to see a water jug experiment !

    They will not do well, beyond tumbling as spitzers do. OTM is not the same as what gets sold as a "hollow point". OTMs are not designed to expand, HPs are.

    If so, then sounds like the 1:11” twist is not fast enough to stabilise the longer 200gr bullet.
    @shooternz’s 151gr bullets are specifically designed for .308.
    Yes, is a 308, my barrel was pretty filthy after that, wasn't that clean to begin with.
    I had a bag of the 151gr too but started with the 200gr going with the theory of bigger is better.
    Used a standard primer and copied @Flyblown and loaded up some 151gr with 7.8gr of trailboss and had a chance to put them on paper and over the chronograph today and am happy with the results.
    Will have another crack at loading the 200gr in the future

    Closer to 40, was more interested in velocity at the time.
    I'm planning on testing them out to 100 just to see what they drop like vs my standard zero.
