Hi Money, sorry for the late response, got sidetracked.......
Berger 105 Hybrids. I don't remember where, but I saw someone recommend zero jump way back when, so I tried it. It does go against "conventional" wisdom, but it works for me. Last time I Magnetospeed'ed, I think my SD was about 6 (?). I don't doubt for a minute that others that are jumping their rounds aren't also getting great results. I used to Moly coat, but found it to be of no benefit nowadays.
I neck turn/neck size only. Neck wall thickness is 0.0135" and my neck sizer button is 0.268" for -0.002" neck tension. I use the same chamber reamer to make my own neck sizer dies, concentricity is great. I get pretty anal about this stuff, but it truly is a hobby, a distraction and a bit of a labor of love. I'm looking for levels of accuracy that aren't really practical for PRS types of competition. I'm older and have some physical issues (can't run or walk long distances), but the younger PRS guys that would recommend against what I'm doing probably aren't wrong (for their needs). I'd probably have to be admitted to the ER if I lost any of my brass......
Just having fun with it, it's worked out very well.
