[QUOTE="Sledhead406, post: 1820229, member: 108747"] It seemed like I was chasing my tail in the past with only powder charge/type changes. A load development thread here on LRH had a .030" seating depth test done right after finding the max pressure.. Game changer. It is fun to watch your groups shrink and/or expand with coarse seating depth changes. Find the best seat depth, then do a ladder test. If you want to try to get more out of it, then fine tune by .005" increments around your best previous seating depth. FWIW my seat depths in various rifles have vary from .05" off lands to .130". I used to believe you had to be right on the lands for accuracy, but accuracy is dependent on each individual rifle. [/QUOTE]
