[QUOTE="Pudgy, post: 2772823, member: 124264"] 1 it takes a minimum of 10 shots to get meaningful results (the more, the better data) Getting low SD/ES has become fairly simple. If I have low numbers but poor groups/fliers it generally because the load is too hot. I keep backing down til I get consistent.2 to .4 groups. For me consistency is the key to low SD/ES. Most important- good brass and bullets (consistent bullet weight and bearing surface) Consistent headspace is often overlooked and has a big impact as well as the right primer. Generally not loading hot helps. Amp Anneal every time, Henderson trim, I full body neck size & mandrel (however know others that don’t mandrel and they get low es/Sd) SuperTrickler powder dispense +/- .02. Good temp stable powder helps to keep things in tune. Shoot ladder in 3-shot groups to find my powder node. Usually if I follow these steps, within 21-30 rounds I find my load. Then fine tune.
