I never asked anyone to completely solve my issue, I asked for suggestions. Than the general consensus was neck tension and it made sense to me, so that's what I went with. I'm not sure why your stuck on the 0.001" difference, other than to pick a fight, that's what my calipers told me, sorry I didn't take a picture and show you, next time I load up some rounds I will take pictures of what the calipers read. I never made any assumption that anyone was an idiot, just some posts we redundant of what was already explained and covered.
