[QUOTE="datsjeep, post: 393885, member: 23150"] Ok Magnum if I understand you correctly. You start with a COL of magazine length - .005. Retumbo seems to have the highest velocity listed with 71 grains being the max. So I would load 5 shots each of 68,69,70,71 After that is where you lost me. Assuming 69 grains is the most accurate you would load 1 each between 68 & 70 in .3 grain increments and shoot them in a round robin (?) to determine where the accuracy node is ????? I dont get it. Then you would reduce the seating depth by .005 to find a sweet spot on COL. Assuming the sweetspot on my gun is somwhere close to the federal premiums I have shot accurately, moving my COL by .005 and 5 shots each would take me 103 rounds. [/QUOTE]
