In PRS/NRL when you are transitioning to another position/prop it keeps the bolt from falling forward and causing a feeding malfuction.
Pretty genius idea.
My T1x will malfunction, my B14-R will actually chamber a round...
Do you really want to get technical? Have you ever gone from the top of a cattle gate to the bottom of one? Have you ever gone from a high to very low position?
Just tilting my RimX caused problems. Some guys literally have rubber bands holding the bolt back. You can always use a Vudoo or RimX if you don’t like a feature. Even holding the rifle pointing to the sky, you reach a point so low it is going to be downwards to get that low.
I rather like it, and specifically asked for it to test.

Throwing a rifle up on a prop and/or barricade easily generates enough force to run a smooth bolt forward. I guarantee you can go to any match and someone will point a rifle at a downward angle at some point. It's not exactly easy to throw around a 20 lb+ rifle for a couple hours.
Correct.
Have it and not needed it? Feature can be removed/ disabled. The detent is also how I keep the bolt from over caming to the opposite side.
The downside of having an extremely smooth bolt, which I found out last weekend at a monthly NRL22 match with this action is that itll bump the bolt forward during fast transitions. Happened on the ladder stage "home improvement". I tend to tilt the rifle sideways when entering port holes or small spaces and slide the rifle up to a smedium. If done fast enough, I've jamed a Rim-X and Vudoo quite often this way
I was recently contemplating how to retrofit something like this or a rare earth magnet to the rear action screw.
their is a unique feature on the bottom of the action if you look at post #147 that will allow a single shot adapter to fill the magwell port of the action. Also CZ457, T1X and Anchutz guys might benefit from it in the future "winky winky"
Provisional patent filed
Happened to me when nesting the rifle into the bag and bumping the barricade stop…. U know, an object in motion stays in motion etc etc.. it’s just enough to strip a round.
Didn’t realize what I was doing until someone pointed it out.
Just got my first batch of dual spring rate extractor springs and tested them this whole afternoon 500+ rounds. These will interchange with Gen 2 and 3 V22s also. It increases the extractor spring pressure while maintaining the same spring rate to control round feed reliable from the mag. Also found best angle cuts for my S7 extractors for this action. Very minimal force needed to send cases flying
Another great video to add to the scrapbook for the birth of the DPG barreled action!
How sensitive is the controlled feed system to magazine/cartridge alignment? Can you have much magazine “slop” and the bolt/extractor/holder will be consistent in picking up and holding correct alignment to feed into the chamber?

To not give to much away, that's kinda the idea to the bottom feature I added and eluded to earlier. It tightens up a lot of that play. I'll demo it and explain to those who attend gravestone match and have a video of it once I get the first patent claims approved. Basically side loading and preloading doesn't effect its reliability regardless of chassis/stock or bottom metal from my testing so far.
I have new V22 mags I tried to today to seek mag options when these launch. 3 out of the 5 kept nose upping 2nd to last round. Measurements are all over the place with these "new" mags at the feed lips. So im going to pass on using V22 mags as what is to be included. Rim-X mags are hard to come by and I've had mix results with L3i mags. Haven't tried their metal ones yet. Pretty much stuck with just moving forward to make my own mag at this point.
Since it uses Mike Bushes extractor design and bolt head, it actually picks up and puts a round into the extractors without a barrel. As im understanding more, single stack mags allow for just one axial force vs a slant fed mag needing a heavier spring to over come two forces to allow rounds to feed into the extractor
