    AR 15 and cast

    Below is a couple of 10 round 100 yard groups I fired a week or so ago.
    The rifle is a RRA Lar 15 with 24" heavy 12 twist barrel with
    the NOE 70 gr rn. and AA 2015 at 17.0gr and a dacron filler,
    this load cycles the rifle flawlessly and throws the case about 4 ft.
    The load on the left is from a cold clean barrel.
    I will play with this some more for sure!!!

    These gas checked, powder coat, tumble lubed. I have a few I was sent from a member here to try out. Did not get into testing with it too much since the Lee c225-55-rf groups decently at 100yds. Thinking seriously about this mold in gc using Lyman 45 with probably carnuba blue. Keep us posted on progress with load development please.

    oven heat treated at 400 for an hour with ice water quench, then back in the sizer for
    felix lube.
