Ted, all it is, is a way to find the sweet spot where velocity stabilizes for a few grains of charge weight. You can see the loads grouped together around 76 gr.
I am just testing a rifle with 215's this am. I had a load worked up in Lapua / Norma brass but the brass seemed to be way soft to me. I have seen this before with Norma brass. Norma is typically soft, but some runs are way softer. At least that's my opinion. Anyway, I loaded 3 rounds of H-1000 in WW brass and shot them, 76, 77, 78 gr. They went into a .3 group. Two in the same hole one a little left. All 3 with different charges were dead nutz for elevation. I think it is safe to say I am in a "Node" for the rifle and load.
Jon, the 78 gr load seems a tad hot for me to in this rifle. No hard bolt lift but I think there was a slight loss of primer tension when I seated new primers. I am going out now to load some at 77 gr.
I will bet $ in a 28" tube , 77 gr with a 215 Hybrid, in WW brass will get me close to 2950 fps. We will see.
