I’ve got a nit-picky question for the metallurgists on the board. I understand the need for anti-seize, 100%. Would there be a problem using a silicone/ceramic brake lubricant in place of the copper anti-seize that ARC recommends? Only reason I ask is that’s what I have already in my garage

Silicone is typically not a recommended lubricant for threaded metal to metal joints, partially because silicone grease often has a poor film strength and it gets forced out of the high pressure areas of the joint. Save the silicone ceramic brake lube for your next brake job.
What really does the job in antiseize is the suspended solids; typically graphite flakes along with nickel, copper, aluminum, zinc, moly disulfide, etc, depending on the version of anti seize you use.
Go pick up some actual anti seize, it's meant for threaded joints. My preference is for nickel based given the bare stainless barrel threads, I use loctite LB771, although it's something you might have to order. You can probably pick up a small tube of permatex nickel anti seize at your local auto store for about 5 bucks; it has more graphite and lower nickel content than loctite LB771, but it's still plenty adequate for barrel to action threads.

How much is there? Is there a "bump" on the back of the bolt like the Mausingfield?
No. The bolt runs quite smoothly and like most every other action, takes just a bit to find how to run the best and smoothly. And like all those other actions, it’s not everybody’s cup of tea. Viva la competition and choices.
I still shoot my roughly 15 yo Stiller TAC30AW action really well, even though it’s loose and has many tens of thousands of rounds through it plus untold dry fire. Yet I do not experience a hang, hitch or any other issue while running the bolt. It about technique.
Ball bearing grease, engine assy lube, Aeroshell 33MS/64, Mobilgrease 28, nickel/copper/metal anti-seize…does it honestly matter? It’s not a brake caliper bolt or stressed suspension component. Just use some lubricant.
Hawk TUAH just spit on that thang?
Well...........depends on what you're planning on doin with it. Or to it.
First ten shots through my rifle at 100 yds. I bore sighted to get on paper for shot 1, then dialed windage, didn’t touch elevation. Pretty stoked with how this turned out
Anyone else miss this post. Really good information that's been out there for a month and I had never seen it.

Properly Testing a Coned Breech for Extractor Drag - Coup owners read this
Folks, Recently we've had a number of guys wanting us to rework prefits for Coups due to the extractor dragging on the bolt face. In May alone it was 5 barrels, 3 of which came from the same member. Those 3 barrels were on the date bubble where it's possible they might have been cut prior to...

My CDG LW is the first action I’ve had with a trigger hanger. Installed a TT Special tonight and adjusted per Ted’s video…wow. Incredible how much effect that had on bolt lift. I can definitely see someone being turned off by the bolt lift with a bare action, think I’ve read a couple complaints in this thread, install a trigger!
As near as makes no difference 9.5lbs suppressed with an Alaskan Ti and loaded with 300WSM. It feels like a toy, and really isn’t terrible to shoot.
Many thanks to Bella at ARC and Russell at Crossroads Precision.
Looks awesome! Mine is progressing but not done yet. Looks like the parallax setting may be a bit tough to read? One of my only complaints with ARC rings is the thickness up top.
Coupled with the fact I don't have a full length rail so I had to move the scope closer to the back ring for proper eye relief you are absolutely right - it is difficult to see the parallax on that scope from the shooting position.
And by difficult, I mean you can't see it at all.
Well I suppose operating it while looking through the scope is the correct way anyway so not too big of a deal. Awesome build!
"Woke up this morning.......and built myself a gun"
Took a break to run errands and handle a few things.
About to get back to it.....
EDIT: Done

I’ve mocked it up and had no problem getting correct eye relief. I could see problems arising for scopes with short tubes.

Does anyone know why my bolt release button is jammed and I can't press it to get the bolt out?
I guess height was part of the question but really the interference between to front portion of the rail and the bell of the scope was the bigger part of the question. The NX8 is pretty short compared to what I’m used to.Teach a man how to fish:

I do appreciate the link though, thanks.
Well that’s exactly part of the height question, now isn’t it? You find that out the same way. Actually read the first post and do the math, using the top of the rail as the part you have to clear.
Yeah the bolt was working fine. Idk though, it was harder than HELL to push the release lever in. I finally got it, but had to apply a level of force 3 standard deviations above the mean.
I’ve had the bolt out a hundred times, was never as hard as that
Ever pierce or pop any primers? Those little bits always settle in the worst places.
Unbolt the action. Bottom side of the action has access to the heat treated retention set screws for the ejector and bolt stop; run them out, clean everything up, lube, reinstall.
I had a bolt stop that was sticky from the get go. Took some measurements and ARC actually sent me a different one that functions freely.

Ahhhh beat me to it!
I have a PMR pro coming in with the CDG. might go with a proof once i shoot it out
I really don’t think that’s true.
I’ve had proof barrels that shoot grade out till 1500 yards.. I’ve also had Bartlein barrels that shoot equally as well.
One of my best shooting barrels has been a Proof, one of my worst shooting barrels has been a Proof. 
Dunno, got a Proof SS MTU in 6.5 CM with 2,800 rounds on it and it’s still holding speed and it’s still shooting great groups.

2800 really isn't a lot for a 6.5 creed but that's a fine start. I wonder if you're the outlier or I am. only got 1100 out of a dasher and was told that was normal. Haven't been back.
still, glad more people are making prefits for good actions. apparently I'm the outlier having two excellent gunsmiths within an hour drive that could either one do my small jobs over a weekend.

Dunno, mate. Lots of folks say 2,500 is about it but that’s prob from PRS/NRL type competitors shooting longer strings of fire and maybe hotter hand loads.
This barrel shoots very good and it’s always been fast compared to others. Dunno why that is either.
@AccuSol-ERN , gunsmith at Altus, and somebody whose services I’ve used and who I absolutely trust, has said on this board that he sees more curved bores with Proof than some other name brands. But that’s just one data point and I don’t know if he was referring to CF or SS. Perhaps that makes a diff.
Cheers

It’s not about the size or shape, but how you use it.
So much comes into play with "barrel life".......from differing opinion of "shot out" to maintenance procedures through the life of the barrel.
Proof makes a decent barrel. In my experience their bores sizes and straightness typically have more variability than others, so they are not my go to recommendation.
All else being equal, in my experience and data gathering "straighter" barrels are less finicky to load for and typically shoot everything well so long as the ammo is consistent from shot to shot. I believe straighter bores tend to have smaller amplitude vibrations that effect bullet release. This is why tuners or bullet seating test show more improvement on barrels that whip more.
I like to think of it with a highly exaggerated example. A water hose left hanging at 90degrees.....turn on high pressure water......straightens out to compensate for the pressure. Now take a hose held out straight.....turn on high pressure water......neglible movement to compensate for the pressure.

Let’s not derail into barrel bitching guys I don’t have enough popcorn for that
I guess everyone can only purchase Bartlein MODBB 26in MTUs from now on.
All other barrels are sub-standard!
Viva la @Frank Green
