Help me analyze my initial load data

[Prison Mike]

Two rifles. Both 6.5 CM. Both .020 off the lands. Both are used for hunting (one is heavier PRS). So not looking for BR precision. I think I’ve got the powder charges picked out. So now what? Is there anything I’m missing?

Should I go ahead and start playing with the seating or fine tune powder charges?

18” barrel 1/8 twist. 140 Berger Elite Hunters. Node @ 39.8

20” barrel 1/8 twist. 140 Berger Elite Hunters. Node @ 40.1

Are basing nodes off of group size or SD/ES? If you had all charge weights with their MV, SD, ES info, that would make it easier to pin point. How many shots per charge weight??

Yea for sake of time I left all the velocities out. It was just a ton of information. Over a hundred rounds total. Three shot groups. I based nodes off of velocities. Points where the velocities would steadily increase then stay the same or go back down slightly. It just so happened to be right where the good groups were which, to me, really stood out.

How many times did you run this test and did results repeat?
