[QUOTE="SidecarFlip, post: 1154762, member: 39764"] You have a couple aspects in play... One, it's hard to manually apply the same amount of 'force' to the press actuator handle each time. That force equates into different seating depths because.... No matter what press you use, the applied force causes a certain amount of flex in the press frame, much like 'springback on a case mouth and that in turn causes deviation in seating depth. I found that out firsthand this summer, loading for my 308's and applying Berger's load ladder. In the end, attempting to load and hold 0.002 increments in CBTO (Cartridge base to ogive) measurements consistently, became an exercise in attempting to apply the same seating force to the press handle, each and every time, almost impossible to do consistently.... Thats hard to do because, not only is your seating force variable, but the actual components come into play. You have the shell holder, the seating die and the movement of the cartridge and case inside the die, all coming together to impart what I term a 'sloppy fit' and it all causes variance in seating depth. I know, been there and done that.... I'm working on a cure and Feenix gets the first prototype to test out. I got my noodle working on it and I've come up with a simple way to apply repeatable force, each and every time to the process.... Stay tuned. [/QUOTE]
