Folks, I went to the range this weekend to do more load development. I'm basically a beginner shooter. I need help interpreting my range results. Target is attached.
6x47 on a R700 trued action Sightron 8-32x scope
H4350 BR-4 primers Lapua Brass (2nd firing)
105 Berger Hybrids
.005" off the lands
Weather 55, wind 0-3mph, 5600ft altitude
No turn neck. 090" freebore
My big questions are: What should I do for my next trip to the range. My goal is a PRS gun. Velocity must be under 3200fps for matches. The gun is a repeater so I really want to stay out of the lands.
Which nodes look good? Why did the speed jump at 40 and 40.5 grains (see attached spreadsheet)? Bad Chrony?
Thanks BB
