    The original Faxon 16" group buy was conventional 5R rifling, with what I believe to be the relaxed tolerances on other chamber dimensions (still within SAAMI specs). The post I copied was #199 in the first 12" group buy. I believe every Faxon group buy since then (12", 20", 18", and 16") has stated 5R-EE in the specs stated in the opening post.

      Why the hell haven't we seen some extensive reports and loads on these 5REE barrels?! I'm so intrigued it's not even funny.

      I HAVE to get a 18" or 20" Faxon group buy now to test the crap out of it!

        Come on Kilco!! It's all right there in front of you on the inter-web!!

        Seriously though, finding information on most web sites is like looking through a pile of encyclopedias with the covers torn off.

        Anyone remember what encyclopedias are?

          My 12" shot real purdy the first time out. Need to get out again to confirm and settle in shooting an AR. My first one you know and it's franken to the hilt. I chopped stuff up befor I ever shot it. Hehe.

          Oh and what faxon is saying is we bought a custom barrel not one of there plain Jain barrels of the rack. No garontee but damn good.

            And then I reckon the nitriding with its higher hardness, should reduce any wear/erosion of these 0.003 (hills) vice the 0.004 (mountains) (with their standard steel and hardness finishes)...
            The original spec 0.004 lands may have been such in order to allow for a certain amount of wearout as shot count progresses. just a theory.

              I am sure that I am not alone in expectantly waiting for test results!

              Most of us don't think much about rifling land and groove details when developing a new cartridge. Drillboss' discussion suggests that might need to be re-thought.

              On the other hand, the Grendel routinely turns in impressive accuracy with the standard rifling.

              One could speculate withiut specifically reaearching that, like so many other features in cartridges, the rifling spec was a carry over from cartridges like the .264 Magnum, the 6.5x55, etc.

                Headed to the PO to pick up a scope. If the weather holds... I'll get some shooting in late today and post results.

                      Haven't been back to the range, but rapid fire 10 shot group was still within the medium red diamond.

                        Why are you doubting him?

                        Mine shot under an inch at 100 with PF loaded 120 Nosler bt. Rapid fired off bags as fast as I could get back on the orange dot.

                          I'm not doubting him, that's a fantastic group... just more interested in "overall" performance of rifles when people post a fantastic group.

                          If you've ever shot something like the "MOA all day" challenge, you know what I'm referring to.

                          I have rifles that have turned in like groups... but to get five of them back to back is another story... but I think you already know this.

                          I'm sure a lot of those barrels are going to produce really great individual groups... the real test of rifle and shooter is "duplication". When you duplicate, then you can say "this is what I can do with my rifle" vs. "this is what I did with my rifle"... not here to start a pissing contest just looking at consistency and duplication.

                            Understandings are correct that it is a Faxon barrel made to my specs.

                            Beyond the difference in the exterior profile, the difference between a Faxon spec and my group buy barrel spec is that my lands are of reduced height: traditional lands height for 6.5mm/0.264" is 0.004, whereas mine are 0.003 to reduce engraving deformation on bullets. There's another theoretical advantage having to do with velocity that I'm secretly hoping for, but only enough guys shooting a large enough sample will bear it out.

                            Group buys of these barrels are found HERE.

                            Drillboss, thanks for digging up that explanation. I thought by now everybody knew that, but I guess I shouldn't have assumed. NOTE: Chambers are totally SAAMI standard with a Manson reamer. No fiddling with chambers here.

                              Looking forward to the barrel coming in...
                              Your specs look ok by me. That's why I opted in.

                                I'm about 99% finished convincing myself I need one of these. The rifling is a very awesome idea.
