I am familiar with moly coating but what is HBN? sorry been out of shoot for a while.
Bench rest guys don't NS brass because the added force used to close the bolt moves the gun in the rest. They are after.001's not .10's

Boron Nitride.
I think. I've heard the term but never really researched it. As long as the bullet comes out of the hole in the end of the barrel & hits what I'm aiming at, good 'nuff for me....
PS = You aroused my curiosity...
Have a read:

HBN = Hexagonal Boron Nitride. It's one of several coatings that can be used on bullet to improve their performance.
I find the quality of neck (ID consistency and freedom from taper) to be better from my lee collet dies than any FL die I have ever owned. If the shoulder on my cases needs to be bumped, I have a body die for that, then neck size the neck.
This is my SOP with everything that I have been able to find collet dies for. For more than a year now, making of custom dies has basically been suspended, so all I have for my 6.5x284 is a FL die and I just got the barrel, so I don't know how the chamber vs the die compare. I do not have a body die for my 243 Ackley, nor a FL die for that matter, these would be custom. Fortunately, it is going to take me a while to work through fireforming all of the 243 brass I bought, so hopefuly I can get the die I need by the time all my brass is fireformed.
I have not had any issues with my method, but then I also do not just buy 20 or 50 shells which then get reloaded in weekly intervals. I plan on annealing by the 4th firing. The ackly cases should require very little trimming.
