    Machines are getting spun up shortly and these will be hitting the market soon.

    Short throw, 700SA footprint. They’ve been tested for awhile, this is all I am allowed to share.

    Dry fire capable since the firing pin never protrudes beyond the bolt.

    They will be available in barreled action only to start.

    Existing mags will work so that’s the easy button, new mags will come after the actions are rolling. One thing at a time. Not sure what the production rate will be so can’t speak to that. It’s pretty exciting nonetheless.

    Just want to make this clear, I comment here on behalf of my own opinion as a consumer and competitive shooter, in case those want to report a comercial account. What I'm allowed to share for now

    That said, their will be no discrimination against leftys as theirs an emphasis of having that option.

    Feedback contributed throughout a year of testing with pro shooters agreed that an 11mm dovetail provides slightly better rigidity for scope handle use picking up the rifle and many scope rail options like MDT, Area 419, DIP. This also allows the market for silhouette shooters in small bore as 11mm dove tail is the preference for weight savings

    AICS compatible with all 22lr mags with a unique feature to allow the use of setting mag height, preventing "universal mags" from seating to high in the action and causing a bolt jam, yes this includes the superior Rim-X mag. Their will be a in house mag offering also once these are in production.

    Barreled action option only, and will seek no lead times as a goal. I believe theirs an agreement to allow other gunsmiths to build off the action given they submit a dealer request and gain approval, attend a 2 day course (no cost) showing how to build a barrel for it. CNC or on a PM 1440GT. To avoid what happened when Rim-X barrels first hit the market. Selected shops will have access to purchase DPG ECM rifled barrels and opportunity to learn advance cnc tooling, machining and reamerless chambering.

    A lot of excitement about this action being produced. I think it’s much needed with another option of a great action to build off of.
    Vudoo is about the only proven action out there at the moment. Rimx is not even in the discussion in my eyes. I threw my new rimx action out in the weeds,done with it! Luckily it’s soft metal so when I run over it with the lawnmower it won’t hurt my mower!
     
    I'll have a separate thread regarding the barrels developed by DPG. In short summary it's the newest technology available utilizing electronic chemical etch machining. Similar to a sinker EDM.
    DPG's family business helped developed some of these machine tooling along with a contract programs needing stainless rods and bushings made for fiber optic data transmission for Elons space-x rockets. The idea was finding the best way to bore a hole straight as even a thou deflection of fiber lines reduces transmission rate through refraction. DPG took this technology and applied it into boring a barrel and now rifling. The metal is forged in California with a proprietary blend in reducing harmonics, softer than traditional 416r, with peak pressure at only 60k PSI, so suitable only for Rimfire.

    A lot of research and testing was done finding how to make a repeatable accurate 22lr barrel. This being a 170+ year old cartridge, it's one of the best documented and theory tested cartridges While many chased after faster twist rates, DPG chased BC. Finding out which barrels produced the highest G1 and RA4 BC over a Oehler 89 BC chronograph. BHN testing and eddy current test of our current match 22lr ammo shown these lead projectiles are not pure lead, having voids and imbalance material. The 22lr projectile is designed to be optimized at 16 twist. Faster twist rates tend to bring defects in these projectiles outward causing an imbalance, hence flyers.

    Shilen select barrels with the ratchet rifling produced the highest BC value at an average .205-.210 over a 50 shot string. However slowest velocity due to the taper lapping, followed by a tie between Mullerworks and DPG at .190-.200 G1 BC and cut rifled barrels at a .160-.180 G1 BC. However, testing mass batches of our well known barrel manufacturers shown a wide performance band. Lead times started reaching over a year. DPG sought after a superior process in producing the straightest most uniform barrel so performance between each rifle developed is identical. ECM allows any geometry rifling without the induced stress in the bore from button rifling.

    EMAG finally released some videos on this ECM process here
