well that not always true, i also shoot banded copper solids for target work that are approx the same length as the 300SMK yet they have a higher BC AND they only weigh 235gr...

go figure...

    I talked with the tech at Barnes also, 575 BC is what he said I didnt have a chance too post. He said something about the bans caused more drag.
    It would be nice if I can get the speed up with low ES and bugholes. I have more loaded hope too shoot by this weekend will post results...

    I purchased a box, but have not yet tried them in my 338 RUM.

    Just looking at it I thought the bc would be higher. I don't think the bands would have much effect on it. In missile work I was involved in flow field dynamics some simulating turbulence over the nose cone of a missile and photographing it. High speed photography showed the turbulence flow field was well beyond the side of the missile and with a bullet I would assume well out beyond the bands or canelure of bullets. In other words the turbulence created by the point of the bullet as it slices through the air is directed away from the side of the bullet depending on the angle of the point. This leaves a little void where the bands would be without as much air flow over it so the resistance of the bands should be minimal. I wish I could explain that better without writing a thesis. May or may not be true with bullets anyway but I would assume the same principles would apply.

    yep you are correct LTLR, and more proof in the pudding is all the excellent very high BC banded solids we are seeing in .338 .375 .408 .50BMG etc... all have bands yet very low drag... i cant see too much dissimilarity between these and the TTSX...

    If i werent so cynical id refrain from saying 'barnes probably havnt even tested the BC of this bullet yet' but thats just me

    Agustus, These are the ones im shooting Projectiles

    'Black diamond 408' is also shooting them in his 375-408 CT, and they are giving him exceptional accuracy... you can read his results in the banded soilds test thread.

    Those predator bullets look good. Doesn't sound like they'd be great hunting bullets. Anyone tried them hunting? Groper?
