Node 6
92.0 grains for 2831fps -15 fps on the chrony at 5 meters
50785 psi

If your BRF does not increase with the higher pressure then
Node 5
95.5 grains for 2948 fps - 15 fps on the chrony at 5 meters
57950 psi
Start with 95.0 grains and look for the above mentioned speed.

92.0 gr. Gemiddelde spoed was 2810. Ek het nie die ander node probeer nie, die dop was baie vol op 92.0 gr. Die maks TPL is 92.1mm so ek kan nie te veel speel met seating depth nie.
