[QUOTE="nkyshooter, post: 2143094, member: 83787"] [USER=11011]@jimbires[/USER] & [USER=102230]@308win[/USER] - finally was able to get the water capacity today - my fired/unsized hornady cases with spent primer all weighed exactly 166.1 (I had weight sorted them before loading) ... with water to the mouth of the case, they were 222.1g ... I calculate this to be 56.0g exactly of H20 capacity ... I see Jim's QL output shows a "usable" h2o capacity of just of 47g ... is the "usable" measured to the mouth of the case? ... or merely to the neck/shoulder junction or somewhere else? What say QuickLoad with this water weight? Also - do I understand correctly that there can be variation by as much as +/-10% (for total potential delta of 20%) between powder lots? And - if this is correct, AND IF my lot happens to be on the slower end, then the weights prior to encountering pressure should therefore be a bit higher? I am leaning more and more towards the chrono being off and I plan to re-run my ladder - this time using the same cases but neck sized only - over a different chronograph as soon as I have the chance. If I can set up both the one I have as well as another in serial, I hope to get either validation or correction on what mine has been telling me. [/QUOTE]
