Has anyone found a way to send ejected brass to the rear more? I don't know if shortening the mechanical ejector somehow change the throw of the brass? Anywhere from 3-5 O'clock would be nice.

I’m in the same boat. Mine ejects forward regardless of bolt speed. 130-230 direction but I’d say more around 2. I’m having to run a brass catcher at matches

They was a guy in the main CDG thread with same issue that replied to me regarding this, that order another ejector and was going to tweak it to see if he could improve the direction of the brass but haven’t heard from him

    That was me. I did the first cut attempt on the new ejector. Shortened very slightly and angled it a little to hit outside edge of rim. Unfortunatly that resulted in no noticeable change. Still get 2:00 ejection. I’ll try another cut soon.

    Is the brass bouncing off the side of the receiver or is it slipping off the extractor and getting launched by the ejector?

    Not hitting receiver, it gets launched by ejector. Might have more to do with how the extractor releases it.

    ShtrRdy, mine isn’t slipping off but can’t speak for the OP.

    I don't have one of these actions so I'm just going off of what I've experienced with other brands.

    It seems the extractor needs to hold onto the rim of the case long enough for the angular momentum to carry it out the ejection port. At least in the 3:00 direction.

    Take the bolt out and hook a fired case under the extractor and rotate it so that the base of the case is against the bolt face. Now you van try just releasing the case to see what it does or slowly letting the case rotate.

    Do a lil Google foo on how a mechanical blade ejectors work, and try that again.......

    That's what I'm thinking. Extractor under spring tension applying consistent inward lateral pressure throughout the ejection arc. Basically extractor is pushing the case slightly back in as the ejector pushes the case over the breakover angle and the result is a outward and forward ejection.

    The test would then be to use a weaker extractor spring so there is less lateral pressure.

    The CDG doesn’t have a traditional coiled spring powered extractor. It’s a metal leaf spring type.
    It has a (high rate) coil spring powered extractor unlike Ted's previous actions. You should be able to see the spring in the bolt head as it's partially exposed. The choice of the high rate spring is what leads me to believe it's extractor spring related.

    I’m a dumb ass. I was thinking of my Nukes and Archimedes. I’ll go delete it now.

    Possibly change the geometry of the ejector blade to manipulate ejection path? Perhaps shorten or change to where it catches the case head as bolt comes rearward. I'd think if it was catching the case closer to edge it's go further laterally instead so far forward of ejection port perhaps? Idk......

    Yeah I figured calling ARC and leaving two messages I would have gotten a call back by now. Figured if anyone would know what to do it would be them

    If I go really slow it might fall out at 3:00. I have a local match this weekend, my first with the CDG, and that will tell me more. Running it fast will surely bring out its true colors.

    I missed this. I’d say 2:00-2:30 shooting 22GT.
    Id call mine 2:30 to 3:00. Checked it this morning a bunch of times.

    As far as angle up and out of the port, it appears to be coming straight out at 3 oclock(if youre sighting straight down the barrel from the shooting position), so it touches the ground only about 18”-24” from the gun. All this was observed while running the bolt fast.

    That’s not bad. I could live with that. I haven’t picked mine up yet as I’m not home right now.

    Playing with my CDG I have two ejection patterns with 22 GT brass when running the bolt back quickly:

    Spent brass mostly ejects at 2:30 with the occasional 2:00 O'Clock
    Dummy rounds mostly eject at 3:30 with the occasional 3:00

    We shall see during the match tomorrow what happens in real world situations.

    Same issue with me running 22BR. Spent brass 2-230 and dummy rounds 3-330 where they should be.

    Did you see in the other post that Thisguy is running an extra dope card as a deflector to help with brass loss? I am trying one today as well. Living room floor tests yesterday give me high hopes.
