[QUOTE="BountyHunter, post: 151502, member: 12"] BillR Not sure that you can ID node by watching extreme spread, just never heard of that and not sure how that works. Maybe you hit in the middle and maybe you hit at one end. Normally a node can be ID'd by a ladder with sequential incremental charges fired and normally 3-4 rounds will have very close MV while the rounds before and after will take dramatic jumps again. If the charges are say .2-.3gr apart that will show you the node start and end. Start tuning in the middle. Would recommend you change one thing at a time and work powder first. Ie stick with increasing charges of Retumbo if 96 is a safe level and leave primers for last IF you need to go there. Your weighing etc looks to be good, so no issues there. The chrony might be questionable. I would say at some point in the future set up your chrono and a someone elses and check them together, particularily if the other is an Oehler. That way you can have some degree of confidence in it and comparison. I had an older PACT that was very uniform in its readings but just a little slower than my Oehler, but at least I knew it was consistent and that is the key. BH [/QUOTE]
