working up a load seems easy peazy to me.
Load up 3 rounds each in .03 increments...shoot for groups at 100 yds... while taking your time with good weather and a stable rest.... look for the 3 groups that look similar in size and placement on paper...that have very little vertical spread upwards. The 3 best groups need to be side by side, not just one good group and then jumping to another one...they must all 3 be side by side and around the same size hole pattern. Then choose the middle group/powder charge, and work with that load, while doing the very same test all over again...but with different seating depths of .03 increments from the lands. You will find a group that sucks down tighter than the one you had with just the powder testing. Once you did all that...you can get real serious by doing the whole test again, but with ONLY changing the primers out... but be careful here, because pressures may get too hot. The most accurate groups will MOSTLY be found near the MAX load area... but there can be a good one with lower charges as well since there is usually two accuracy nodes.
