Has anyone tried using HBN -- Hexagonal Boron Nitride?
Allegedly it does what moly was supposed to do - just much better.

I'm very tempted to try this as it seems easy to apply to bullets & even barrels - Like Microlon just easier!
The main aims for me would be to reduce wear & improve first shot accuracy.

from what I have read, most barrel wear is caused to the throat area by the erosion caused by the blast and hot gases, rather than the bullet wearing the rifling. No amount of lubrication, Molly or otherwise is likely to stop that.

Exactly!

How come norma claim that is drastically improved the barrel life of the 6.5x55? They did a study on it a couple of years ago

Allegedly the HBN seems to protect the barrel steel against the flame heat & thus reduces erosion.
I'm still reading up about it but it looks like it has better properties than moly in quite a few ways.

Can you direct me to that Norma claim? I'd love to read it.

I think one way to approach this is as follows.

We know the throat and leades burn out before the rest of the bore shows any real issues (as a rule).

In my brief time with F/FTR I saw many start with Moly and bin it. I also only ever saw one use HBN.....and was not the next FTR world champ as a result.

IF you purchase a rifle that has (for whatever reason) been moly treated, then it makes sense to keep on going, otherwise unless there is a proven, deeply grounded case for it, dont bother. You are better off dry snapping or watching the wind.

Unless folk are in the BR/F open department they will probably never see any difference so are probably better off shooting conventional, consistent ammo and getting to a point where they can tell.

Condescending?....not really, its something I am becoming more aware of every time I shoot....being crap and all that.

A lot of faffing/fawning/rutualistic bullshit goes on which half the time is wasted when the user gets their arses pummelled by someone shooting RG or boggo factory ammo.

I am trying HBN on a 6mm SLR .... the reason being (as mentioned above) the claims for extended barrel life, extended cleaning cycles etc.

Other than periodically borescoping to check wera etc I have no idea how to truly verify any benefits BUT.....it is SOOOOO easy and CLEAN to apply that I would recommend any Moly users to swap over.

I may never get major benefits ( but I might!) but the effort involved is negligible so why not?

Should also have mentioned that the 6mm SLR brass is reputed to contain most of the 'torching' effect within its extended neck.....time (and round count) will tell!
