    New build report

    My build consists of:

    Ruger lower with Rock river parts
    Anderson upper
    BCG and bolt from Brownell
    BCA 20" 5R fluted barrel

    I got to shoot it a few times yesterday. It showed real promise with 100 gr nosler ballistic tip with a 1 to 1 1/4 group at 100 starting with 28 grains 8208 at 2610 fps.

    Factory Hornady 123 ELDM didn't fair very well with a 3 inch group at 2480 fps.

    I believe they could have been into the rifling as when I tried to shoot my Sierra 120 gr loads the first one stuck in the riflings. I got a measurement and reseated them deeper.

    I will get to shoot it again tomorrow and give another report.

    You might check if your bullet is getting into the lands. All my handloads at 2.245 were way deep in the lands. I had to back them down to way way under spec to get them off the lands. Mine is with a 20" non 5R barrel though. I wanted the 5R but the are always out of stock.

      Thanks, that's what I'm finding out. I'm having to seat things dealer than spec.

        I was shocked at how short my OAL had to be to get off the lands.

          I had a good range report today for my new build. It shot the 100 grain nosler ballistic tips in less than a half inch group for 5 shots. The load was 29 grains 8208 at 2677 fps average.

            Good to hear. Did you see what your OAL had to be to get them off the lands? I checked my friends Saturn Liberty yesterday and it seems its got even a shorter throat than my BCA.

              The 100 grain ballistic tip is 2.250 to the lands. Others I tried were considerably shorter.

                  I took my first deer with my Grendel this afternoon. The 100 grain ballistic tip went through both shoulders at 60 yards. It had considerably more damage on the entrance side than the exit side.

                        I like the Nosler BT but they do have a tendency to breakup on the front end. I like them for coyote but have never been a fan for big game. Year ago I shot a bear with a 180 gran BT and it did so much fur damage it was unbelievable
                        AR's make shooting fun again!
