[QUOTE="LRHWAL, post: 377534, member: 5418"] I'm always amazed at how many new threads start up when you are away for a bit. It took me a while to find this again. Thanks for the replies. MikeCR, I think maybe we went past each other a bit. Yes, I agree barrel timing and harmonics are affected - but I think only because velocity is affected (or am I wrong on this??). I'm thinking that if ES is really low (lets pick an arbitrary low number like less than 5FPS for 20 shots), measuring capacity doesn't matter, as capacity only has an effect on velocity. This is really my question, if it's not affecting ES, does it matter at all and can capacity affect something other than MV? I'm guessing if pressure builds slower or quicker you'll see it in the MV numbers. I'm headed towards wondering how much capacity variation is actually relevant and at what point the variation is worth worrying about. Yes, I agree, nothing wrong with it, but there's this laziness thing....:D Gene, I agree on skim turning and found that it actually made a difference. Lastly, whats the easy (least messy) way to measure with water. I'd reseat a spent primer back to front and weigh it before seating, but filling to a consistent level bothers me. Is the drop of detergent the best it gets? Thanks again! [/QUOTE]
