[QUOTE="justgoto, post: 953254, member: 17125"] When you develop a load you need to things to happen that makes for long range precision, the velocities to have a low extreme spread, and small group. So would first look at the groups finding something with a minimum of height difference, and not too extreme of a width, (unless you had high winds,) and shots not on the outer edges of the entire ladder. So the first two I see are 3 and 4; they are 1/4MOA apart; with a 17FPS difference, (the cartridge containing more powder at a faster velocity.) I would consider that a node, but [B]I would try a charge weight [U]between[/U] those 2 shots[/B]. One way I can eliminate shots from being a node, is by looking at similar velocities not grouping together. We can see that with shots 11 and 12. Shot 10 is the same velocity at shot 11, yet they are very far apart. So when you're near that velocity, you're in a vibration. With this new information, I would venture to select the charge weight between 3 and 4, the charge weight between 5 and 6. If shot 7 and 8 are in the same hole, a charge weight between those 2 may produce a good load. [/QUOTE]
