Ryan - do you mind explaining the the why behind the 0.004 neck tension? Versus the .001-.002 most are used to?

I found that the accuracy windows were slightly wider. ES shrank substantially as well. I shot 7 shots over the labradar yesterday while shooting at 1000. ES of 5 fps. first 3 shot group was 1.9" of vertical. the second 3 shot group had .4" vertical. This was while shooting in mirage with a 15x tangent theta and a bipod with rear sand bag. Proof Research carbon fiber barrel with 1.250 shank. First group was a hair low on the target. Over corrected for vertical on the 2nd group. Last shot made a slight adjustment and nailed it for waterline. Trued my kestral 5700 elite. Shes ready to roll now. There was a 5 mph wind while shooting. I wasn't overly concerned about the little bit of left and right on the groups.

@rpierce is this with the Berger 230g's and N568?

Yep. Cant get any better than that. Especially with a 15x scope and a bipod LOL.

Here’s some data with 6.5prc. Looks like I found a great node around 60 grains. I lost some data…first time using LabRadar. I’m getting much more fps than Berger data said. And I am well below max. I am okay with that. Maybe it’s the 215 primers?

I can back this up in my 28 Nosler. Once I stepped up to .004 smaller bushing over loaded neck my ES was cut almost in half.

Here is what 568 did in a 28 nosler and 195's 3050FPS. I'll take this accuracy all day long.
This one is throated a little short for the 195, I believe OAL was 3.66 for a 3.7 mag box
