Really...about all we can say with certainty is that," When I do this, this happens." Every thing else is supposition based on a guess as to what is happening. "Cut and try", and take notes. Once you have made enough seating depth changes, in a systematic and organized manner, and have notes as to what happened in each case, you will start to get a feel for this area of reloading. Typically, if a shooter has a long time between range sessions, does not load at the range, at least for these types of experiments, and does not take good notes as he works, he will stumble around in his disorganization, and only accidentally discover a good load....or not. Sadly, this is pretty typical of a lot of shooters.
