[QUOTE="Michael Courtney, post: 682176, member: 28191"] In the 5.56mm test barrel, HBN reduced the friction on the 55 NBT by 15%, the 62 BFB by 12%, and the 55 TTSX by < 1%. The report is not available on the web that I know of. The earlier report describing the method was posted here: [url=http://www.longrangehunting.com/articles/measuring-rifle-barrel-friction-1.php]Measuring Barrel Friction In The 5.56mm NATO[/url] To me, these modest friction reductions do not warrant the time, effort, and expense of coating with HBN.
