[QUOTE="Gamesniper19, post: 2899421, member: 95013"] I run ladders with a single load per...rather than 2 shot or 3 shot groups. The result should be a clear and obvious horizontal node in a charge family. I will load up to 16 rounds with apx .3 grains difference per. For 30 N I ran 79 79.3 79.6 79.9 80.2 80.5 80.8 81.1 81.4 81.7 82 82.3 82.6 82.9 83.2 - began to see pressure 83.5 - sticky bolt and stopped Accuracy node from 81.7 to 82.3 - I then load in the middle at 82.1 and begin group tests. Why middle, cause that is the sweet spot and gives my load .1 to .2 grain "powder measure variance" to ensure consistency. Then seating to fine tune and done. Generally get single digit SD's with this and extreme spreads under 15 which at 3014 fps is excellent variance. [/QUOTE]
