Velocity nodes and ladder tests

[VenatusDominus]

Two fascinating articles regarding load development, the standard "ladder test" approach, the "Satterlee" approach and velocity nodes. The first is a shorter and less technical article. Both have short summaries at the end if don't want or have the time to read them in their entirety.

The process can be as lengthy and technical as a man wishes.
Or a helluva lot simpler, just preference.

TLDR: The "velocity flat spots" evaporate once enough samples are shot.
Watch the targets first Grasshopper, then the chrono.....

looks like a node just over 60.0 and again just past 61.0 It would be interesting to know the quality of the rifle, components and the shooters credentials, as well as what the target showed "optimal charge weight" style. I haven't looked at the two links in the OP but I will. Fun stuff.
