[QUOTE="Mikecr, post: 306531, member: 1521"] By asserting that your group shooting represents best efforts towards accuracy, You essentially declare conclusion with inquisition. So you're not really looking for contrast, but validation.. For responses desired, you might ask instead "How can I tighten my LR groups?" But since you wondered, I follow RockZ's approach pretty much. While fireforming brass I watch my chrono readings , and pressure signs, for reasonable pressure, velocity, ES and feedback for my QuickLoad powder file. I take a best guess there and do the same varying seating depth. Then I measure H20 capacity on each case discarding departures from the bulk. Now I shoot a warm bore ladder(15min/sht), with my best guess again. Then I either make adjustments for further ladders or venture into cold bore accuracy/ES testing with another best guess. All the while I'm 'hoping' for a good shooter with adequate -predictable -accuracy. If it sounds like I don't know what I'm doing, or like it's a crap shoot. You're right. But keep in mind that to date, not one human understands tuning, or could 'predict' a shooter from squat. Accuracy has to be verified as it really is a crap shoot. [/QUOTE]
