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

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.Last edited by Troutguide; 10-07-2017, 05:36 AM."I rarely give a definite answer" - TG

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."Down the floor, out the door, Go Brandon Go!!!!!"

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.shootersnotes.com

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.
