I've decided to play with some loads to improve my long range shooting, 600 yds +, in two of my current hunting rifles. I chose them because they are the most accurate I have out to my normal hunting distances.(-1MOA) I have reloaded for about 40 years and played with a wild cat or two. I have never seriously shot beyond 500 yds. I may never shoot at anything but rocks and other inanimate targets beyond that range but want to see how well I can do. So getting to my question, would you start with seating depth adjustment and then powder charge or vice versa? I have a comparator and am very familiar with Case to Ogive OAL. I realize that accuracy will be a process of adjusting both, one at a time but I am curious where you would start. Both of the guns are SAAMI spec chambers and mags.
