Increasing neck tension with moly/hbn?

[Longshot]

Any of you fellas using hbn in particular found that you need to increase neck tension at all? I'm using hbn and am not getting consistent results like I should be and am wondering if neck tension might need to be increased a bit.
For reference the caliber is 6xc and I'm shooting 105 hybrids mainly.

Two thou. NT has worked well for me, no matter the cal., with coated/uncoated bullets.
Seems a good balance for low runout and consistent ignition/velocities.

That said, 1/2 MOA is about as good as I ever consistently get with my best rifles.

In 6.5/55, with 139gr moly'd Scenar's ... NT experiments showed irregular vels. at 1 thou. NT, and increasing runout's at 3+ thou. NT.
Results were similar in .308 testing.

Somewhat less sensetive to neck tension, if the bullets are jammed, per my experience.

.002 for Moly coated.

bringing up an old thread but, I played with hbn this year, the .5micro size.
I found the coating made for increased friction in seating the bullets even if I only use .001 neck tension, it made for inconsistent seating depth vs bare scenar 6.5mm bullets and the difference in force required on the press was easy to notice. It also caused a wider fps spread according to the chrono and it showed quite clearly at long range in my testing.(wish I could have done a bit more but I think I got enough for my curiosity)
Only thing I liked about it was the somewhat lower fouling.
I won't bother with it anymore personally, maybe others had more luck.

I believe it was in Zediker's Handloading for Competition book that he mentioned 1 thou tension for the brass spring back and another thou for the tension for 2 thou on naked, and add another thou for coated bullets which worked for me with moly. I found with hBN in .308W that 5 thou gave me a tighter group over the 3 thou neck tension (less than 2" at 400m).
