Desert Precision Gunworks 22LR Action Updates

There is a buffer system that will allow different manufacturers magazines simply by unscrewing a buffer. There will be a video soon to show this feature.
Correct. After sending about 30 fouler shots, my first 40 rds were averaging 1048. Eventually I believe it was up to 1058. It was incredibly accurate with that lower velocity. By comparison my Vudoo was 1098 in the heat of the afternoon in Huntsville. It was incredibly humid as well.
Since I test every rifle before leaving the shop, I've been able to test all sorts of theorys in 22lr accuracy. Barrel speed seems to fall into barrel length / accuracy "nodes" and certain barrel manufacturers perform best at these nodes. Chamber Jam points also play factor in this. For majority of barrels at 22-24" I've found they typically like lots that shoot around a 1065-1090 range out the muzzle. 25-26in at 1035-1060 fps range and prefer less cartridge jam. Thiers typically a 20-30 fps difference in my barrels due to the alloy steel. DPG barrels run slightly slower with the trade off of not being lot picky. Other barrel manufacturers with tighter bores or thier 416r grade steel may run faster.
Those that shoot Eley, at 26in, brings velocities down to 1085 and keep you away from transonic/super. I personally don't see accuracy degradation at distances 300-400 yards even with ammo that is shooting 1030 FPS. I have an AR22 that will mirror a bolt gun accuracy at distances like this. Again, this is based off quantified data recorded over 4K 22lr rifle builds.

After 25+ years of chasing the precision rimfire game I have come to this exact same conclusion. About 15 years ago I settled on 24”-27” being my preferred barrel length (really the 25”-26” is my first choice). I believe that it slows ammo down far enough away from the transonic flight to create a much more stable / consistent bullet flight & the extra time in the bore allows for the soft bullet (which may not be perfect in shape or seating) to better stabilize while in the bore.
I have said this many times over the years here and in other forums but I truly do feel the longer barrels in rimfire help absorb the inconsistencies found in even the best rimfire ammo: primer compounds, charge weights, neck tension, bullet lube etc all have more variation from lot to lot and bullet to bullet in the same lot with 22lr vs precision loaded centerfire.
I couldn’t agree more!
In general when it comes to accuracy performance alone, .22LR shooters need not be concerned with keeping away from transonic/super velocities.
If anyone shooting .22LR is concerned about transonic turbulence, it's not an issue with the vast majority of .22LR ammo. When transonic turbulence occurs, it's when a supersonic round slows down into the transonic zone of speeds which is from about 1340 fps to 890 fps.
Most .22LR match ammo spends much of its flight within the transonic zone, with the typical round falling out of it around 150 yards.
The bugaboo of .22LR high velocity ammo inaccuracy is directly related to ammo quality not ammo velocity.
The advantage of using slower .22LR ammo is in the fact that it drifts less in the wind than faster .22LR ammo. Comparing two rounds at 200 yards, one at 1050 fps and the other at 1125 fps, every 1 mph of crosswind causes the faster round to drift about 0.15" more than the slower round.

I agree, the other aspect is engaging sub MOA targets at 150 yards and in where mach triming is starting to play a effect. I found I fight more vertical stringing with rounds that are shooting 1100 fps or more at these distances compared to those at 1080 or less. Harder to true up my Kestrel also as I tend to DSF more points at 150 to 300

To anyone coming out to Gravestone tomorrow Shayne is going to setup a side stage with the DPG rifle. Come give it a look.
Latest Patent Pending Innovation from Kenny.......as I mentioned earlier, these allow for the use of most of the current rimfire mags (Vudoo, RimX, Bergara, etc......) to work with the DPG Action. It also helps eliminate the typical variations and loose tolerances between various chassis manufacturers. End result is just overall better feeding into the chamber. These are swappable from the magwell, no need to remove the action from the chassis.
I did forget to note that one of these is a single feed adapter.......sorry.

Got the ok and first Patent claims approved and the OK from the Patent attorney to discuss. This im excited about.... Maybe a bold claim, but I think I found a way to eliminate mag feeding issues Permanently while having the ability to adapt other mag platforms into a Rem 700 clone chassis and action
Also, got the first couple of actions back from Nitride coating. Significant difference in feel and function. Shot 400 rounds just this afternoon and barely any wear

I have never been this excited about a product in my life. I cannot wait to get my hands on one of these. Awesome work Kenny!
My unqualified opinion is machined delrin likely makes the most sense between controllable tolerances and cost.
Kenny made it clear that he is making lefties so I think we will be alright. I’m buying day one if he has lefties available on release.
Their will be lefties available when these are released for purchase. Boss of DPG is a lefty and made it very important to offer left options. See post #37
Also, just wanted to get a general idea how much interest is their for a opposing ejection port??
Right Hand Bolt with left port eject??
Left Hand Bolt with right port eject??
Tag your responses if this is an option you guys want. Most BR folks prefer this configuration for ease of use to load. Ive been told PRS guys can benefit for direct LOS of the ejection port incase of malfunctions, trade off spent brass flys in your field of view

@EagleEyeShooting @J_D You guys need to stop teasing me, I now have to carry a fire extinguisher every where I go, this money is burning holes!!
Got to handle the new rifle of J_D yesterday. Beautiful machine work and it flat hammered.
I actually shot it first thing in the morning from it being cleaned overnight and the first 5 never made the hole any bigger at 50yards. That’s impressive in its self. The name of it is amazing and I am very proud that Kenny is choosing to come show the world what I think will be a game changer at my match. It’s going to be a great day

Honestly, I am not smart enough to know as I haven't started BR shooting. The closest is "approximating" my heavy chassis with an ARCA front rest adapter and front rest with a paired rear rest, but still using RH Bolt and RH port.
With Kenny's new mag block adapter to adapt for single feed...
FOMO....I'm in for a RH BOLT / LH EJECTION PORT setup. Luckily I have another spare chassis (MPA BA Comp) unused, now it will be earmarked for this future action.

Big thanks to everyone who attended the Best of the West 22lr Match at Gravestone. We had dozens stop by and checkout our new rifles. It was an honor to R.O stage 1 and see many talented shooters clean this stage. @Shayne Ward. Hosted an awesome match and thank you Gravestone for having us! @J.D for keeping us cool and hydrated
Lots of folks showed overwhelming support and excitement of the new action. Lots of great feedback and positive reactions. Many got to see in person these features work in person and we are excited to push forward in production. We are taking feedback to decrease bolt lockdown pressure by adding more caming force and reduced chamber jam. Both rifles ran through 700+ rounds at this match without issues except a broken 3D printed mag buffer. Very surprising to see it still hold up during the heat as we expected this to break earlier.
Big thanks to MDT for the support and 1 on 1 feedback from the pro shooters. They where super excited to try it out and absolutely loved how It performed and ran. Cleaning a 250 yatd KYL ending with a 2in plate rack right out of the rifle case this morning cold bore without the rifle being cleaned.
Im excited to know only minor improvements are needed and taking feedback on ejection port preference. We are soooo close to a perfected product and still ahead of schedule!!
Our team enjoyed the company of Mr. David Lott @DI Precision and his valuable feedback and expirence in this sport and building some of the best 22lr rifles.

Thanks for posting this outing update and stoked that the feedback was helpful and only resulted in minor tweaks that you are considering to fold into the released version (and still ahead of planned schedule!)
Have you ever tried a left-hand bolt? I used to do the same thing as you and got a left-hand rifle, and it was night and day.
Yes I did try a left hand rifle, but no I never gave it a chance. Was being pestered none-stop and I just said yes to get the guy to be quiet. Ran a magazine and said no thank you. I do need to give it an actual try, just to see
It’s huge when you’re shooting on the clock. Pulling your support hand off of the rifle to run the bolt is detrimental to accuracy. I can assure you that it will be well worth it. I used to be in the same boat as you.
You mentioned you may be able to get a buffer made so that you can run T1x or CZ457 magazines.
How likely is this to happen, or is it just a maybe?
Being able to run T1x mags would be a game changer for me, definitely a very very appealing feature.
Yes, But will be implemented later. Priority will be to have a bullet proof functioning action and get it to our 44 clients that swapped. Ill be focusing on AICS mags for the initial launch, then CZ457 as I already have majority of that modeled and rapid prototyping for T&E

Yeah perfectly understandable.
I imagine AICS will be the most popular mags by a long shot, but having other options would be sweet.
Hey Kenny, just to be clear, my request is in addition to my current order which would be for the initial offering of RH Bolt/ RH port and the a second order (when offered) for RH bolt/ LH Port.
So, more orders for you, less spending capital for my wallet.
