[QUOTE="browning442, post: 1470726, member: 31891"] Gents, I'm looking for your take on group interpretation. Fairly new to load development, know the basics of the different ways of doing it. So far, i've been initially doing 3-shot nodes, about 5-6 nodes total, starting at max w/quickload and backing down, that are 0.5 grains apart. I've heard of different ways using ladder and OCW tests. May try those going forward to save some cash and barrel life. Long story short, my 280 AI is what I'm testing for. These happen to be with the 165 Sierra Game Changers. My info is on the target and my velocities are posted as well. I want to get everyone's take on: 1. This method for load workup. Have a few people that say that really velocity is only thing that matters on the initial workup, whichever method you use. 2. Brass resizing - For a while i was neck sizing only, however i've gone to full length sizing and bumping the shoulder back .002 from a fired case. 3. Interpreting these velocities and groups. I'm using a caldwell G2 which has worked better than my prochrono did, but there are a couple velocities that are "outliers" it seems to me. 4. Powder - Reloader 26 has given me good speeds but generally been more temperamental with the 280 AI. My thought was the 62.0 to 62.5 node was where i should start and adjust seating depth. But I'd like to get some experienced thoughts, and also see if with the given groups, anyone thought seating depth wouldn't tighten them up enough to continue to use this powder.
