Coup De Grâce, New Action from American Rifle Company, $899 WOW!

My CDG is mounted in an MDT ACC. Also running AW mags and it is a royal pain to get them to seat. Have to slam them in to get them to seat but once seated it runs flawlessly. Super stiff to push the mag release to get them to drop out as well. I’ll have to message MDT about a different latch as well.
I contacted them about my HNT26 and they sent me new latches and it works perfectly now
 
I took a file to my mag catch. actually I had my gunsmith show me. it was so simple I felt stupid for asking for assistance but it was my first time on such a project so I wanted experienced hands.
if it's too tight, file a tiny Lil bit more until it feels perfect, then stop.

I'm having a great time with my SA CDG as .308 PRS rig. Is there any hope for a Medium Action CDG, maybe even in LW pattern?

I sent them a product suggestion email for the Medium Action CDG....no response but I didn't really expect one. I just wanted to put it on their radar. Maybe you/others who are interested should send them emails as well. I think most businesses keep some sort of tally for product suggestions.
 
Semi retarded question here.
Can you buy a savage small shank barreled nut prefit and then simply have a smith do the cone breech afterward ? since you control the headspace via the barrel nut, it should work ?

You would need to have the chamber cut a little deeper to allow for the coned breach. In a large enough caliber it will work without the coned breach.

Has anyone tried to exchange a bolt head with ARC? Cause I have a brand new CDG magnum bolt head that I received when I purchase my long action and I don't need two of them.
Yes. The bolt head exchange is pretty straightforward if you are at least mildly mechanically inclined. Ted’s bolt disassembly and assembly vid is very helpful.

I bought mine with a Lapua bolt head and then changed my mind and bought the magnum head to make a 7PRC. The swap was not hard.

I think he is wanting to exchange an unused one with the company for a diffesrent one. Sounds like he has 2 of the same bolt head.
 
Guys, I have a really stupid question.

I've had my CDG for about 6 months. I'm trying to insure it, but I need the serial number.

Is it that really long number engraved at the magwell opening (starts 15HSRxxxxxxxx)? I didn't see any other numbers on my action, but I've never taken it out of the chassis, either.

Check out https://gunandtrophy.com/gun-insurance/ for insurance. You don't have to give them Serial Numbers upfront unless the single gun value is over like $5k.

Also Eastern Insurance has a similar policy.
 
Is there a general consensus on fixed bolt handle vs pivoting? I know there's talk of the pivoting not being ideal with light triggers, but just from a functioning perspective what's the benefit of one vs the other? Using my gun for PRS, I've never shot a gun with a pivoting bolt handle before.
The folks I've spoken with said that 99% of the time they don't even notice it. Probably that 1% is when they need a little extra primary extraction, and feel the handle pivot rather than having to smack it up.
 
Am I the only one who kind of prefer the Archimedes to the CDG ?

I've got 4 Archimedes and 1 CDG. I like both, but I kind of give the edge to the Archimedes as well. The opinions below are my own...

Archimedes positives:

Lighter and smoother bolt lift than CDG with equivalent rate striker springs. The Archimedes being pivoting bolt handle only with no allowance in the bolt rotation for an extraction cam has shallower cocking ramps providing a lighter bolt lift. My Archimedes with a 22# striker spring has a lighter bolt lift than my CDG with the 80N/18# spring, and the 22# spring in the Archimedes provides a lot more energy to the striker hit on the primer than the 18# spring in the CDG. The CDG with the optional 100N/22.5# spring will hit the primer as hard as the Archimedes but then has a far heavier bolt lift than the Archimedes with a comparable 22# spring.

Generous bolt body to action clearance is more tolerant of dirt IMO. My CDG bolt can get slightly "draggy" coming back when dirty because the bolt body to action clearance is tighter. The negative of this extra clearance in the Archimedes is the bolt droops and flops around a bit when open and the cocking plece can rub on the top of the stock/chassis, and if your chassis has a bump/step where the cocking piece rubs it can cause a bump/hitch when running the bolt. Some say this clearance makes the bolt easier to bind when running fast, but I've never encountered that issue.

Conventional full feed ramp and standard diameter bolt without a 6 o'clock lug means the magazines sit higher in the action and this helps feeding .378" diameter cases like 223AI that can be a little tricky to get feeding smoothly in the CDG. I've got one of my Archimedes feeding 20 Vartarg out of 223 AICS magazines with zero issues... tried that combo in my CDG as a test and quickly gave up, the CDG doesn't play nice with those small diameter stubby little cartridges, lol

Rotary bolt release makes it nearly Impossible to accidently drop the bolt, you have to twist that bolt release past the detent like you mean it and it will only fully rotate to the open position in one narrow range of the bolt travel.

I prefer the larger leaf spring style extractor on the Archimedes to the pivoting claw/ball/spring arrangement on the CDG; fewer parts and no worries about dirt or debris making the extractor ball and spring sticky. They both work though.

This one will probably get some disagreement, but I like the removable scope rail on the Archimedes. Allows easy replacement for different cant or even extended rails for scopes that need extra eye relief (not sure anyone makes an extended rail, but it is possible.) I recently used one of my Archimedes for a lightweight hunting build and swapped the rail to one with less cant because the lightweight hunting scope I was using had limited elevation travel. The rail on the Archimedes is keyed to the receiver for recoil and side impact resistance and uses 5 large flathead screws to hold it down. Never had one work loose or move. I know the integral rail on the CDG will never come loose or move, but you have no option to change the cant or get an extended rail if needed.

CDG positives:

Trigger hanger allows easy trigger timing for smoothest handoff of cocking piece from cocking ramps to trigger sear.

Integral scope rail will never come loose or move, but hopefully you ordered the right cant and don't need an extended rail.

Dedicated bolt handle bias spring means the bolt handle takes much more force to pivot than the Archimedes, so in the CDG you don't feel the bolt handle pivoting while running the bolt unless you have a stuck case. Compare this to the Archimedes which uses the striker spring to also bias the bolt handle, and because of that the bolt handle pivots much easier which means you can feel it moving a bit when running the bolt quickly even if you don't have a stuck case. I wish the pivoting handle on my Archimedes was as stiff as the CDG's pivoting handle.

Toolless takedown of the bolt and a simpler bolt takedown/reassembly procedure than the Archimedes. Need a couple of tools for the Archimedes bolt. Fewer "small fiddly bits" in the CDG bolt compared to the Archimedes bolt.

Can run AW mags, can't do that in the Archimedes. AW mags are awesome if you're running a cartridge that will feed from them.


I like them both. My preference leans towards the Archimedes, especially if you're going to use it for .378" diameter cases or a cartridge that only has single stack mags available (my Archimedes are 2x 223AI, 1x 20 Vartarg, and 1x 7 PRC, so all single stack mags.) If you're running a cartridge that will feed reliably from AW mags I leans towards the CDG (my CDG is in 22GT using AW mags and works great.)

I'm disappointed, but not surprised Ted discontinued the Archimedes in favor of the CDG. Streamlining the production flow makes perfect sense, and the CDG with the action body not needing bolt lug raceway cuts like the nucleus and Archimedes it's surely quicker and cheaper to machine. That CDG is still a nice action, but I wish the Archimedes was still available as well.
 
That's what I'm doing as well. Arch and Nuke for my 223rem and 7 saum (single stack AICS) and most likely a 22ARC once I burn my 223rem.
CDG for my 22 and 6.5 Creed with AW mags
I also prefer the Arch bolt stop over the Nuke 2.0 and the CDG. I actually had to get a replacement bolt stop for one of my Nuke because it got rounded and sometimes wouldnt catch the bolt if I ran it fast.

i have a 7 saum in long action being built. Do you think the AW mags would work? its coming with an aics mag. i also ordered a 300 prc mdt mag to see if it works. is a masterpiece built rifle in the matrix pro 2
 
I run several Archimedes and two cdg all pivoting, obviously on the Archimedes. Diamond in everyone at the lighter end of the spectrum but not ultra light, I like a little feel on my finger. Never an issue with anything.


I have Diamonds in other guns.....wanted one for my CDG.

I went with the 2-stage Diamond and set it up with light sweep and normal feel on the wall / break. First time having a pivoting action.

There was almost no acclimation period to use it.

Not trying change the subject here, but has anyone found a method to smooth out the bolt body and bolt stop friction point? I use Lucas heavy duty gun grease and oil on all my actions including the cdg and they run really smooth. Every now and then I can feel the bolt body "skip" across the bolt stop.

Wonder if Ted could make a prototype action with a ball detent or small roller bearing in that area to reduce friction?

I love my cdg actions by the way....I'm just nit picking like a woman 😆 🤣

Lapping compound helps
 
That's not possible. Stop rides in a fluteless channel.

Okay, I was just spit-ballin' that one - I don't have one on hand myself - yet. I'm working my way forward through the entire thread and saw quite a bit of early discussion about flutes/no flutes early on.

Currently around page 50, starting to skip a couple pages at a time as that's apparently when everyone was in the early "are we there yet???" stage of waiting on the pre-order ;)

I have 4 of these, including 1 w an un-fluted bolt. If you want the the smoothest, most vibration free CdG cycling, that's your route. The crowd talked Ted into flutes, but he knew what worked best.

Yah... when I saw that the flutes are mainly on the top, solid on the bottom, I figured they were just for aesthetics. They do look pretty. Nice to have the option, I guess.
 
Can you expand on this?
The coned breach has gone through a couple of revisions, and there is a new extractor revision as well.
Best to blue up the extractor and breach cone, and run the action through a few feeding cycles to see if you're getting any contact with the coned breach.
