Anyone have any issues with creep on the second stage of a TT Diamond 2-stage in the CDG? I have the hanger setup well, the bolt is butter when opening/closing. I can feel the first stage fine, hit a wall, feel it creep, and then the large wall that lets the firing pin go. I've tried a few different weights on both the first and second stage but always have creep. Want to ask before contacting TT warranty department.

I haven't noticed that with mine. not saying it isn't there but I don't notice it if it is.
Thanks! I hear good things about the combo, just want to make sure there isn't a step I forgot like an idiot.
Just assembled my CDG build which includes a TT Diamond 2 stage, and I don't notice any creep at all.
Make sure to set the first stage before setting the second.
Just was watching this video and saw another rifle using the cam type bolt to help extract, this time from the British in the early 1980s:
Question for other folks running .223 in their CDG. How much tuning do you have to do for the average magazine? I know there were a few posts in this thread about mag nodding.
Any recommendations for good DSSF .223 mags? I got one from MDT to try before I buy more, but it has had trouble feeding the last few rounds. (Bolt slides over the round as it slides forward I. The feed lips).
I was able to fix it by carefully observing the feeding issue (slow motion video) and sanding down some bowing in the polymer walled feed lips to flatten things out, but I hesitate to buy more until I ask around and see what other folks experience has been . These seemed particularly finicky.
What AICS mags do you prefer for .223? How reliably do they feed In the CDG? I know chassis has a part to play here as well. My magwell is tuned very tight

The recommended mag from ARC is Accurate Mag. Either a 5 of 10 round mag. I have a 223 CDG and all i had to do is use an adjustable mag latch to set the correct height so it does not drag on the bolt. There is a spacer that comes with the action in the bottom of the box for AICS mags. If you put upward pressure on the mag it will jam into the bolt. Possible that you have to modify the chassis to get the space to fit.

I'm using the 223 AICS Accurate Mag with no issues.
Nice, thanks! I'll try the Accurate Mag ... mags.
Chassis is an MDT with adjustable mag latch and tuneable magwell, so very happy with how it gets things snug and high in the action.
I didn't get a spacer with my CDG, sadly. Yours came with one?

The spacer was easy to miss in the bottom of the box, very small.
FYI- with a little modification to the Accurate mag I'm able to load 223 out to 2.540". That's enough for anything I've loaded so far.
Just checked all the packaging materials again. Even took down the boxes and shook out the padding. No spacer 
You're talking about that little tab that sits between the action and the chassis near the the feed ramp, right? The thing Ted showed in one of his videos about mags he said we probably wouldn't need?

Yes the little Silver tab.Just checked all the packaging materials again. Even took down the boxes and shook out the padding. No spacer

My CDG throws brass pretty forward maybe not 1:30 forward but not 3 o’clock either. I have been running an impact for years so I’m used to a much further back ejection.
Not a HUGE deal but annoying and having brass fly off a platform is annoying.

Dang it. Ok. Might be worth another call then I guess. Thank you very much!

Here's the tab in the plastic bag that it is shipped in.
Just so I am certain, we're talking about these, right?
AICS .223 Rem / 5.56 NATO Magazine
Note: This product is a complete magazine, not a kit. Existing rifles with M-24 type 308 bottom metals can be retrofitted to smaller calibers by simply changing the barrel/action to the selected caliber on the same stock. For savage rifles, this magazine will only work with rifles originally...

Thanks for the pic. Definitely did not get one of those tabs. I was very thorough to check everything I received since a few parts of my order got mixed up, and I had to work with ARC to get it straightened out.
Yes & pick std feed lips for ARC's/CRF actions.Just so I am certain, we're talking about these, right?

Can someone post their fired CCi450 primers? After 550 rounds I am starting to have primer failures. Not sure if it is this lot of primers or my action after re-tuning my trigger.
Check your trigger hanger, ensure it is still tight and hasn't reduced your pin fall.
Primer failure as in failed to fire?
It’s easy. Cut the little nub off shown in picture.
Second pic shows modified on left & factory on right.
It's tight and pinfall seems more than adequate
How deep are you seating the primers? Have you taken a cartridge that didn't fire apart to see if the primer fired?
I recently ran into a problem with large rifle primers (CDG action) where they had to be seated deeper than .004" and less than .010" deep or they had problems with not firing. Seating them .010" deep broke some of the primers (CCI 200). After taking them apart I found none of the primers had fired even after 4 or 5 attempts on some of the rounds. Seating them .004" deep wasn't deep enough, but they fired on the second try. I've never used large rifle primers before so thinking this was just due to my inexperience. Loaded my last batch to .007" deep and had no issues.
I use CCI 450s on my 6.5CM and never ran into any problems with duds. Seated them anywhere from .003" to .010" deep and never had an issue. So my issues with LRP may not be related to your issues with CCI 450s.
I have a feeling your ignition issues are not related to having to be seated 005-009 primer depth, I think you have something else going on. I seat all my primers to where I can feel slight crush to bottom of pocket. With lapua brass srp that's usually 003-004 deep, alpha srp 001-002. Adg lrp 003-004. This is all I have ever done for prob 20k rounds of rifle fire. Only time I've ever not had primers ignite, was headspace issues caused by a deep chamber/too much shoulder bump upon sizing, or the primers were 40 years old and not stored well. My CDG 6bra, Alpha brass cci450 primers are 001 below case head, prob 600 rounds never once an issue. Other cdg 65cm with lapua seated 004 bout 500 rounds, no issues. As long as a primer is flush of the case head, you're good. Seating the primer deeper into the pocket past contact to the bottom of the pocket is not going to do anything for cocsistency of ignition. Benchrest guys do experiment with primer depth, but that's an accuracy thing.
Measure the shoulder with you bump too one brass you're having issues with and compare that with a deprimed fired case. If you're fire forming to an improved chamber (think 6br to dasher) you may need to set a false shoulder, or jam bullets into lands 10-15k to keep case head from coming forward upon firing pin contacting primer.
Accurate-Mag top, MDT Bottom. with 80 grain .223
I removed some material from the front of the Accurate-Mag with a drill press to allow the COAL to clear the front.
What has your experience been with that MDT mag? Do you have feeding issues in the CDG?
I just ordered a few Accurate Mags with regular lips to try out. I wish someone made an all-metal .223 AICS mag, but I haven't been able to find any this far.
I have used the metal/polymer insert .223 MDT mag without issue.
I have two of them and they work fine.
I don’t think I have ever seen a .223 mag without the polymer insert.
Unfortunately... I use those .223 magazines with my Mausingfield M7, my CDG is built as a .308. Both magazines work but I do think the Accurate-Mag are better.
You need a certain amount of round on top of the round to enable double to single feed and the width of the aics pattern makes that unsuitable for 223 sized brass, so even with all metal mags it will need a cover to fit the aics magwell, then there is the cost of the dies for the stamping machines, so the plastic insert is what you get
I was replying to @HemiPowrd as to his primer depths for consistent ignition. Your pin depth looks good in the photos, if the primer compound is properly installed in the primer and mandrel is good they should be popping. I haven't really looked that closely at a Cci srp's underside to see if there are visual anomalies present. I know I always hated decapping an unfired primer, fearing ignition, but nothing has ever happened, although I've only done it a few times.
Anyone got a LA 308 boltface CDG? Looking at one of these or an Atlas for a 280AI build, wanted to see if the CDG is worth the 4+ month wait for the long action 308 version (short action 308 and short action mags are popping up every so often on the PX but no such luck for this configuration)
Brother has one, no issues running 30-06 with a non coned breech savage Prefit from X-Caliber. He loves it so far but it will really get tested in a couple weeks once rifle season opens.
I have a feeling that we are past the 4 month waiting period of this release. Seems like they are getting closer anyway. I'm guessing the number of first week orders was insane.
The latest report in this thread of a shipping notification is from 25 May. That's just over 5 months lead time, and I think it was a long action. The short actions are still a month or two behind those.
I don't think they're quite caught up yet. A realistic wait time is probably 5.5 months. And that's assuming they're shortening their lead time and aren't effected by large orders for OEM actions.
I got the idea from some show off at the range who had a blue AI! 
Wonder who that is?!I got the idea from some show off at the range who had a blue AI!
My barrels came in today. 6.5 Creedmore. I'm building on a Xylo chassis. I haven't put it together yet, but the AIAW mags don't seem like they are going to fit in the Xylo.
If anyone is using a CDG in a Xylo with AIAW mags, did you have to do anything to get them to work?

Your Action needs to be cut for AW mag and the chassis may have to modified depending on the action. It’s not meant for AW mag.
The CDG should be fine at that end… but chassis is another story.
They specifically designed the new coupé de grace action work with AW mags… and they are so smooth and nice, as you probably know.
From ARC website
Magazines
- Short actions are optimized for AIAW magazines
- Short actions will feed from AICS magazines but require an adjustable mag latch or modification of a fixed latch
- Long actions will accept AICS 3.850"/CIP length magazines
- For 223 Rem and 5.56x45 NATO, use metal Accurate Mag 00100-0037 (10 round) and -0038 (5 round)
- MDT Polymer 223 mag is not compatible with the Coup De Grâce
I just realized I was in the Coupé de grace thread!
whoops!!!!
