The Noveske N4 is at least sub-1.5 MOA. And it's 2x chrome lined.

I've had this conversation with the guys at Robarm couple of times, and the consensus was that nitriding would be cheaper for their operation.
I do wonder, and this is just me thinking out loud, nitride makes the barrel surface harder and more corrosion resistant, but what about heat? Does nitride reduce friction between the projectile and rifling, or increase friction, which in turn would increase heat build up?
Dave,
Just so I'm tracking on this:
Is the purpose to reduce breakages of the extractor itself?
Or
To get a wider bite on the case rim and allow more extraction force without deforming or ripping the rim off?
Or
To move the pivot point to allow more extractor tension without extra heavy springs?
Great point LL. It would be helpful for the purposes of this discussion if people identified issues with the current design that they have ACTUAL firsthand experience with or complaints they have based on ACTUAL use. "I hear chrome lining is bad for accuracy" is different than "I needed to shoot a guy in a man-dress at 200 yards and believe that I missed due to my chrome-lined barrel".
VB: I'm not sure about your heat question but it is a good point. And yeah, I had a feeling it would be a cheaper process.
LL: why don't YOU go read the current thread on this site about accuracy expectations and see what YOU gather from it. ;)Also, why don't you stop picking out 1 basically meaningless comment in my post and reply to the general content of it? I have shot it just not for groups (I've shot plenty of CL'd barrels, who hasn't) I honestly think it will be just fine but that thread is a little concerning for ME. In case you didn't understand, I'm referring to CL barrels in general and not just about my particular sample.
Oh my, Rob I don't think you are gonna find anyone who can blame a missed shot in combat on a CL'd barrel. There's no way to determine that.
If there's a process that is equal to or better than CL in protection, wear etc. and at the same time bumps up accuracy, I can't think of any reason not to suggest it. That's not even taking into consideration that it may very well be cheaper.
Anyway, there seems to be some others who would like to see nitriding as well. Again, it's just a suggestion.
Can you link to the other thread for those that want to follow along. If it's the thread I think you mean there is whole lot of conjecture and mythology there too.
FWIW, as a general rule of forum etiquette if you're going to mention another thread the best practice is to link to it.
Well I hope that's the case.
This was the 1st forum I have been a member of so no, I didn't know it was proper etiquette. Lemme try to figure out how to link.

Particularily concerning to me was the long post with Pat Rodgers stating the standard is 4 MOA. Also noticed most of the people who mention good accuracy (2moa and under) are speaking of non chrome or stainless. I would not be happy 3-4Moa with M193
Again, I really didnt wanna turn this into a thread jack.
