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 vs. charge weight. 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. The OCW method fires three. Both work. Both are looking for the same thing: a forgiving charge band that’s repeatable across temperature and time.
