[QUOTE="Lonewolf74, post: 1470848, member: 96274"] The ES can easily be chrono error. The most reliable and probably also most cost efficient way to double check your powder charge is to get a beam scale, they don't drift like the digital's do. However even if your charge master does drift a few tenths it's not gonna cause a 100+ fps velocity spread. Some may disagree but I would always start with a seating depth test. Once you've found a sweet spot for a particular bullet it should remain constant except for maybe some fine tuning a few thous later on. From where your at now I would do a seating depth test at your lowest charge weight and find what seating depth shoots best. Then reshoot the charge weights at the seating depth sweet spot you found, omit 64 grains if you found pressure there. If once again 62-62.5 are your best groups and have similar point of impact like they do now then that's your node. [/QUOTE]
