    Ogive Radius, calibers: 13.0
    Meplat Diameter, inches: 0.071

    Would love to try them in a 7 RUM. I tried a search and it was pretty fruitless.

    Thanks.

    Here's the scoop, Matrix 190 VLD. I believe Matrix is a calculated number, might be good for comparing Matrix bullets to themselves but not as an actual G1 BC.

    Slightly inflated then... Doesn't really look to be that much more impressive than a Berger 180 VLD.

    Here is some recent information on B.C. testing the Matrix 190 grain bullet by two of Australia's best long range champion target shooters.

    How did you work that out?
    What velocity is it valid for?

    Came from the rocket scientist Bryan Litz and that was his G1 average over the entire velocity spread.

    That's about the same as the 180 Berger...

    Advertised b.c.'s by custom bullet makers and die makers are often grossly exagerated! Most of the factory bullet makers are starting to be much better about realistic b.c.'s. If it looks fishy and you see no reason for a bullet to have an excessively high b.c., there is probably a VERY good reason. B.C. is nothing more than sectional density and profile..........Rich
