    With some perfect still conditions for load testing of the 75gr HPs today I jumped at the chance.

    I fitted the 6x45 barrel to the cz and loaded the five H4895 rounds into the mag.

    I messed up here as I forgot that I gave the barrel a scrub clean after the last test so the first shot was 40fps fast and high.
    I should have loaded some fouling shots first but meh.. take it for what it is.
    Other than that first shot it was a very small group.

    The chrono readings were as follows:

    3002, 2969, 2960, 2960, 2961 fps



    The BM8208 were the next group and they also shot pretty well with a bit more velocity but also slightly flatter primers.

    The string was looking good except the second to last shot. Not sure what went on there.

    2985, 2982, 2981, 3000, 2986 fps




    I could back the BM8208 load off .5gr to match the H4895 velocities to see If the pressure drops back a bit too but I think Ill just run with the H4895.
    Just as @Mathias mentioned in an earlier post you can see the BM8208 primers a quite a bit flatter showing higher case pressures than the H4895 on the left.
