[QUOTE="Mikecr, post: 2957360, member: 1521"] This is where QuickLoad and a chrono really helps. With it you would work up across a chronograph, calibrate QL, and see what your pressures are. That much aside, pressure 'signs' are different animals and dependent on the build & your reloading plan. Often, they are not actual pressure problems. I do a test I call MyMax, where I work up in charge with new cases while measuring case diameter at the web-line (widest portion). I'll see growth, then leveling off (plateau), then a step change upward. That step change point has always worked out to SAAMI max (for me). It is a point where FL sizing would be [U]required[/U]. If I run into issues along the way,, primer issues,, brass flow at bolt face,, poor extraction,, I stop to deal with those before continuing to MyMax. With later load development I usually end up choosing a load near or just below MyMax. [/QUOTE]
