I've achieved several great loads using the Satterlee test. I do .5 increments then explore flat spots further with .2 increments. Most flat spots produce good loads. Some don't. Just gotta find what your rifle likes with each particular bullet, powder, etc. combination. I'm currently trying a more accuracy based OCW test right now. Just got my scope back so I'll continue with that test and see how it compares. Plenty of people have said the Satterlee test is a waste of time but my .5 moa 338 RUM with an ES of 6 would disagree
