Load Ladder
A load development method where you shoot a series of charges in small increments, watching for accuracy nodes and pressure signs as charge weight climbs.
Pick a starting charge, increment in small steps (0.2-0.5 gr depending on cartridge), and fire one round per step over a chronograph. Plot velocity against charge weight on a chart. Where the plot flattens (small velocity change across multiple charges) is a node. Where pressure signs appear is your ceiling.
The Satterlee method runs one round per charge, while the OCW method fires three at each step. Both approaches work well in practice. They are looking for the same thing: a forgiving charge band that stays repeatable across temperature and time.
