But you do realize in this test that the AMP press really has nothing to do with your observed improvements. You had an easily identifiable issue with your load process ( which even you said you were aware of). You switched to a new method of seating, Wilson in line dies, which you say, solved the problem (and is understandable). So what did the AMP press contribute? In reality, you could have used Wilson dies and an arbor press to fix the problem ( or just better screw in dies).
Also in this test, did you use lighter neck tension that you mentioned before? If so, which was it, better seating dies, less tension or both? And again, what did the AMP press contribute? While it may have shown your seating pressure to be relatively high, most people can feel, particularly with a Wilson die, that kind of too high pressure, or do the the math, maybe .007 is too much and I should try .002 - .003 tension, and then test that. Again, no AMP required. Another example would be , guys on my F Open team use anywhere from .0015 to .005 neck tension because they have tested that and determined which neck tension gives them the best results on paper. Again, no AMP required. And the trace results are different but the scores say each work just fine.
I'm not the guy trying to pick on you, in fact I'm pretty impressed with your 338 SD's- is that a 250 gr bullet?, I'm just the guy asking the questions bc many people have been down this road and are still scratching their heads as to what benefits the press brings.
