I’m not aware of any load development method which doesn’t use any target analysis. Satterlee method is as close as it gets, since the focus is upon velocity.

I’ve shared here, multiple times within this thread and many, many times elsewhere on this and other forums, that I have used many different methods. This particular method works with high efficiency and efficacy for the stated particular flavor of competition

Your interpretation isn’t apt. I’ve made no statements suggesting these methods are apt for a short range benchrester, nor have I stated precision isn’t required for short range benchrest, nor have I stated common short range benchrest load developments aren’t apt for their game. This isn’t a load development thread, it’s an OCW method thread. If you like what you do for short range benchrest, great. OCW is one of a handful of methods which work very well for long range shooting sports.

I’ve stated here multiple times, precision rifle competition and long range benchrest have different demands of the load, such the load developments are different. My experience in long range benchrest, apprenticing under older and more experienced shooters, involved extensive Audette Ladders fired at 600-1,000yrds to find a charge node which minimized vertical dispersion. For precision rifle competition, we’re not shooting groups, and no target is smaller than 1/2moa, with most falling between 1-3moa. But we might be shooting out to 1400yrds any given weekend, with no sighters.

As I stated above, a load with 50fps spread might only have 0.1” unresolved vertical dispersion at 100yrds. Very few shooters are capable of disqualifying a load simply based on a 3-5 shot group which has 0.1” extra vertical. That same 50fps spread would translate to 10” of extra vertical at 1,000yrds. I can shoot a hundred rounds in load development to compare ten groups of 10 rounds to determine which load prints a 7” tall group, vs. one which prints 17” vertical. Or I can shoot 30 rounds across a chronograph and know whether my group at 1000 will reflect my group size, or simply reflect my velocity spread. Considering I need to verify my velocity and confirm my nodes before each match, that’s 80 rounds a few times a month, instead of 24. With a barrel life of 1200-1500 rounds, and matches eating up 250 rounds each, it’s pertinent to shoot as little in load development as possible.

Horses for Courses. Audette’s Ladder, Newberry’s OCW’s, Long’s OBT, and Satterlee’s Velocity methods all work very well for long range shooters and competitors.
