Mike, am I correct in understanding you refer here to the never-released successor to the "original" 15-rounder?

Just curious. I have two of the originals, and they run flawlessly in my 1st-gen V22 in an MPA BA Comp chassis, as long as I jump down/turn around/touch my toes/utter magic incantations before and during loading.
Yes, the one they worked on after I left, pictured below, but never launched. The project was abandoned after more than a year.

For the RimX Shooters:

Now that the V-Series Magazine design is locked and I'm working on the X-Series, can you guys provide a bit of feedback regarding function?

Please don't get me wrong, this isn't in any way a rock throwing question; they did a great job on their magazine. I'm asking because I'm nearly finished with a study that I purposely didn't start until I designed the feed stack in the V-Series, which carries over to the X-Series.

I'm just curious about the impact of adding key features that I've used from the start in what I believe to be a well-executed magazine.

I have a RimX and have had very few problems with feeding. Once I got the mag heigh adjusted correctly it's been fine. The only real issue I've had it a few weak ejections when cycling the bolt.

I built it up on a Manners MCS-TCS that was inlet for a Coup de Grace action (which is a R700 clone) with the Manners mini-chassis.

Find marc wright on FB and get one of his tensioner springs. Helps with ejection.
 
Hit the ground running early this morning and, as I mentioned in yesterday's V-Series Pre-Order post, the X-Series, X2210, is moving in parallel to the V-Series magazines.

I expect to be in Phase 1 Prototyping by the end of the week, so again, a big THANK YOU to the RimX crew that provided invaluable feedback.

For those that like to run extensions on lesser capacity magazines, I'm envisioning the extensions from Hoz And-Shield and MK Machining will work on the V-Series and X Series if the stack shift can be accommodated. We shall see.

But of course, 12 and 15 round capacities will be available for the X-Series for those that would rather not use an extension.

MB is there a confirmed weight for production units? I read the answer before comparing favorably to rim-x, but I don't think it quantified the actual number in ounces/grams. etc
The weight data I have now is generated by material properties studies in SolidWorks. I have a RimX mag in hand and I also modeled it as part of an in-depth study, and what I know at the moment is the 10 round V2210 is very close in weight to the RimX magazine (according to the properties study). I haven't conducted the properties study yet on the X2210.

Once I have LRIP parts in-hand, I'll compare actuals to the data, and if need be, I have room to remove more weight. The RimX magazine has some areas where the wall thickness is a bit thin for my liking, and I stuck with Aluminum for the base plate. Additionally, there's more hardware in my magazines due to the added features and functionality.

Hope this helps.

A quick update:

Parts Kits:
Since the parts kits aren't coming together as quickly as I'd like, and since I have various parts arriving, I'll be shipping individual parts to satisfy the outreach and get rifles up and running.

Gen 2/Gen 3 Repeater, V22S Single Shot Firing Pins, Gen 2/Gen 3 Cocking Pieces, all Threaded Pins, Trigger Pins, Extractor/Pusher Pins and all Springs are about to be available for shipment.

What's to follow will be Extractors/Pushers, Bolt Releases (all Gens), Gen 1 Cocking Pieces and Bolt Shrouds.

V-Series Magazines:
The Pre-Order is going very well for the V2210 and the structure for production is working out to be a beautiful thing. The outreach I've received from folks that want to be a part of this is truly blowing my mind. I have a couple more things to validate and the 12 and 15 round capacities will be available for Pre-Order when the higher capacity V-Series move into production (within three weeks).

X-Series Magazines:
The internal Design-For-Manufacture (DFM) review was completed early this morning and the X2210 is in Phase 1 Prototyping. Once I make it to Phase 2 Prototyping, I'll be looking for some RimX shooters near me to do some range testing. The range test will involve the Phase 2; 3D prints and I'll supply all ammo. Anyone interested in participating can shoot an email to [email protected].

Detachable Bottom Metal (DBM):
The DDG Standard M5 and M5x DBMs are slated for LRIP following the LRIP (in process now) for the V2210.

Receiver Wrenches:
The Gen 3 RH Receiver Wrenches had to go back to the vendor for a revision and are being turned around as quickly as possible. I have Gen 1 RH Receiver Wrenches in post processing now (tumbling, etc.) and will be shipping them as soon as they're out of post machine processing. Gen 2 RH Receiver Wrenches are inbound to me and available for shipping as soon as I have them.

re: possible weight reduction in the mag design...

Lighter is better for "true" dead weight mass that sits behind the balance point, ie mass whose removal doesn't negatively impact function.

In PRS this helps get lighter rifles at neutral balance, and in other disciplines with weight limits, it prevents forcin rebuilds of existing rilfes that are within <1/2 lb (or whatever) of the current weight limits in their existing configurations, etc.

This is just my personal take but figured I would throw it out there completeness.

I'm sure that the answers are somewhere in this comms train, but I can't seem to find it. I don't recall what I've read and where I read it. So, apologies, Mr. Bush:

1. For stock/chassis selection, this is a Rem 700 footprint, yes?

2. And, will it function the way you want it to with other people's bottom metal, in my case, Terry Cross's for his Combat stock? That isn't, I suppose, essential, but if for nothing else by cosmetics, it would be nice. I'm not interested in a chassis, not intending to compete, planning on a general purpose precision rimfire rifle, and having been seduced by the aesthetics of the Sentinel S.W.S. rifles. They're simple cool.

Thanks for your patience.

No apologies necessary, DK.

The action(s) is/are based on the physical footprint of the Remington 700 Short Action and compatible with any stock or chassis, including the one from Terry, that's advertised as Remington 700 Short Action compatible. Also, any DBM will work with it as well and Terry does a really nice job with everything, he puts his name on.

For those continuing to reach out about pre-ordering the higher capacity V-Series Magazines (12 and 15 Round Capacity), I'm in the throes of validating the V2212 and will be headed into Phase 1 Prototyping by the first of next week.

The V2215 will follow, and I see nothing preventing me from accepting V2212 and V2215 pre-orders within the initially communicated three-week time frame. It's likely I'll accept pre-orders for the V2212 just prior to the V2215, so things will continue to move in parallel.

I truly appreciate the continued interest and support, and I am blown away by the outreach to test the X-Series magazines when the time comes.

Hi Mike,
I had a couple of further questions on the actions you are working on, hopefully general enough that you can. Will you be using melonite on the actions? I have a gen 1 and a gen 2 V22 and much prefer the melonite over ceracote. Secondly, will you be offering LB/RP and RB/LP as options?
Thanks,
Drew

Hey, Dude, they won't be Cerakoted. Provided I can get batch to batch consistency with Salt Bath Nitride (Melonite), that's the way I'll go, and if not, some form of vapor deposition. And yes, all bolt and port configurations.

Heads Up:

Aside from a few finishing features not seen in the attached rendering, the V-Series Magazine Line is complete. I'm weighing the impact of a 17 Round version on part density for the tombstone, so I've not made a final decision on the immediate availability of a 17.

The V-Series and X-Series magazines are being made on a five-axis horizontal, and the plan is to design and build one tombstone for what could be a total of 16 parts (each half for eight SKUs) if the 17 Round version doesn't negatively impact part density. So, stay tuned on the progress of working out final details for the 17.

Now, focus is shifting to bring the X-Series alongside the V-Series, so everything continues to move in parallel. These magazines are feature rich, reflecting input from experienced NRL22 and Precision Rifle Series Rimfire competitors, a lot of which was shared in many posts within this group (thread). Also, as of yesterday, DeLane Development Group has committed to being a sponsor for the NRL22 to continue to support this community.

Lastly, for those emailing and messaging about the Pre-Order for the 12 and 15 Round V-Series Magazines, I expect to open the Pre-Order for the 12 Round later next week. As fluidly and accurately as things have unfolded over the last three months, momentum is continuing to build.

Thanks to all and reach out if you need anything.

What’s your timeline for the new actions?
In all seriousness, I'm not thinking much about timeframe for actions at the moment as eight different magazines (if I do 17s) go into production, along with DBMs. I believe I can start prototyping actions within six months and will dial down on this over the next few weeks.

As we're discussing magazines of various capacities/lengths, a question with an introductory explanation:

Decades ago, now, Jeff Cooper talked about what he called the Ohlmstead factor, eponymous for someone I never met in that circle who raised the concept orignially: It's the vertical distance between the highest and lowest points on a rifle in its usual operational orientation. In the precision rifle ambit, that is probably the vertical distance between the magazine floorplate and the top of the elevation turret on the scope. It was/is supposed to measure what Cooper thought of as the "wieldiness" of the gun, the idea's being that as the setup gets larger, particularly above the bore line, the more "tippy" it becomes. That means the more effort it takes to keep it in true, uncanted vertical.

I can neither find nor remember the details, but the range five to six inches seems right, pulled from the hazy depths of time. I don't know that it's a consideration here, but with a big scope up top, I reckon it could be. And maybe a longer, thus heavier magazine could mitigate it...though the change in weight, hence inertia, as rounds are chambered and the cartridge stack gets shorter, that might not be the case.

Any ergonomically minded folks here have any thoughts?

I think you could omit the magazine hanging below the stock, since that wouldn't add to tippiness....unless the weight of the rifle was resting on it?

I like where your head is on this, as I'm a huge fan of Jeff Cooper and the "handy" rifle. Primarily, what Mr. Cooper was referring to, was the usefulness of a rifle based on package, in field expedient use from prone to standing (off-hand, slung, etc.), and everything in between. I used to live eight miles from Gunsite and spent a lot of time there with a rifle in-hand.

One of the platforms he promoted was the Steyr SCOUT Rifle, as he provided input on its creation. It was incredibly light and also had a bipod built into the forend. Although I didn't have a Steyr, I did have a custom-built SCOUT that I used for most everything and with the Ching Sling, there wasn't much I couldn't do with that rifle.

As it relates to the input I've asked for regarding the various magazine capacities, the use case is mostly unrelated to the "handy" concept promoted at Gunsite. However, there's a reason I'm doing four different rimfire actions. ;)

Hi,

My Vudoo action ended up with some rust (nothing on the barrel) mostly on the outside close to the recoil lug and juste below the rail. Managed to remove most of it with oil except inside beyond the lugs (any idea how to get there without removing the barrel ?)

Also any idea how it happened ? Shot it a month ago and put it in the safe. None of the guns have any rust and the Vudoo never got wet. Never had rust either even on blued steel guns stored right next to it so I'm wondering how a SS action with a coating can rust so much while there's zero rust on the uncoated SS barrel. Bolt is also rust free. It's not sweat either since I don't touch the recoil lug area

At least damage to the coating is minimal but I'm scared to take it out.
 
And it continues....

Lots of finishing touches on the X-Series Magazine Line today and, presto chango, the X2212 is generated. From here, I can change a number and the X2215 gets spit out and I'll post up the trio within another day or so. So, the line is nearly complete and parallel development continues.

Over the last few days, I've been receiving questions via email, this group and a forum about the timeline for Rimfire Bolt Action availability. I'm not yet saying much about the timeline for actions as I continue to focus on the V-Series and X-Series Magazines, Standard M5 and M5x DBMs, Comprehensive Parts Kits, Receiver Wrenches and a few other things.

Having said that, I should be positioned to speak more about the actions within the next 30 days.

Thaks to all who've reached out and please feel free to do so anytime.

How do we amp up interest in furthering the DDG Test Fixture into the next phase and into production?

Consider this a call to “action” (pun intended) as this peaked my interest and won’t let it die on the drawing board (figuratively and literally speaking).

It's Official:

The X-Series Magazine Line is in Phase 1 Prototyping and thanks to the fluid movement of the V-Series through prototyping, I expect the process for the X-Series can be accelerated.

The focus in getting this project locked is to validate parts density for the production work-holding convention. Based on the outcome of that process, the determination will be made if the 17 round versions of the V-Series and X-Series will be possible with just one tombstone.

For those just tuning in to the DDG Group, the V-Series Magazines are backward compatible with the V-22 Repeaters and the X-Series are compatible with the Zermatt RimX. Both Series are vertically adjustable while inserted via a provided, validated process.

The actions I'm working on will feed from either.

The problem is being able to ship to non awesome places regardless if they are marked or not. But obviously there are 1000 other ways to get them there.
Yeah, so we make/sell mag extensions and I hear a lot of this domestic and international. I also travel to a decent amount of matches and I just keep our extensions in my truck for people who want them, but can't order directly. I have some customers who live in adjacent states and bulk order for their buddies that live across the boarder.

Mike, is there a way we can talk you into not engraving the cartridge capacity on the side of the mag? There are a lot of friends out there who do not live in awesome places, and not mentioning the capacity can help.
I would rather not, but I have to mark caliber and capacity to be in compliance.

Can you engrave it with Roman numerals? Not too many people know how to read those numbers nowadays.

Note: I can't stand hear some kid bitch about his math teachers when they made us add, subtract, multiply and divide with Roman numerals!
