    Well after fireforming brass this week and breaking in the barrel. I decided to take the new 22 BRA to the rifle range early this morning and do some testing. The first target was shot at 300 yards tuning for seating depth at 34.0 grains of H4350 and a 450m primer.

    The second target was shot at 500 yards with my best seating depth from 300 at 33.8, 34.0 and 34.2 grains same powder and primer.

    This afternoon I’ll test primers most likely

    450m BR4 205m and the S&B for what looks to work best. I’ll take the best 2 of today and retest again tomorrow. I need get another neck bushing as well and see if the rifle is going to prefer a tighter neck tension than .003

    Bullets shot today we’re Sierra 80 MK moly coated.

    This makes me very excited for my 22BR! That's wonderful accuracy and performance. What was the wind like?

    If you get a moment, I'd love to see a picture of a loaded 22BRA, by itself or next to something for scale. Always enjoy seeing what they look like.

    If you look on the pic of the targets it’s listed on there. I missed it to!
