Hey, careful there with the age discrimination! Don't forget, the older BR guys have spent a lot of their retirement money on your designs...That would be pretty cool. And I agree, the 50 yard BR guys only care about what was new 50 years ago, when most of them were in their 40s.

C’mon BR guys, I’m kidding.
Just kidding back at you!
And by the way, what, in your experience and data is the optimal setup for 50 BR shooting? Is it still 16 twist?Hey, careful there with the age discrimination! Don't forget, the older BR guys have spent a lot of their retirement money on your designs...

Thanks,

Yo, Dude, too funny, and I appreciate your sense of humor.
Yes, 16 twist; there's not a lot to be gained from tapping into more available BC for the BR stuff. Although my nine twist does very well at 50, the BR application is dependent on other criteria that the BR folks have dialed in very tightly.
MB
If I understand the “issue” is that BC is changing as the velocity is slowing down and is critical after a certain distance (for sake of argument 150-200 yards, could be after 100 or after 250, but at some greater distance than 100) and ways to compensate for better BC (to counter air resistance and destabilization) is play with barrel twist and/or bullet shape/profile. Are there other means to alter BC or other means to help prolong the destabilization and keep as much accuracy and precision for all ranges 0-500 yards (ideally)?

The relationship between MV and POI with .22LR is not always consistent. While this isn't always clear at 50 yards, it is undeniable at twice the distance. That is to say, for a variety of potential reasons, by the point where distance is twice the usual BR distance, MV doesn't always predict POI.
When shooting at much longer distances, how consistent is the relationship between TOF and accuracy performance?

Mornin, Dude, you've not missed anything. The bolt stops are inbound, as are the threaded pins and I have springs on hand. I'll have the complete kits for these ready to go in another week or so.

Quick Update:
Receiver Wrenches:
The backlog of Receiver Wrenches is out the door via USPS Priority, and if you ordered as recently as this morning, it's on the way to you now. I appreciate the patience as I dealt with getting an issue sorted.
Single Screw Cocking Pieces:
I'm down to less than 100 in stock; they're going fast, but I'll be issuing another PO if you're not quick enough on the email to me to get squared away.
Magazine Progress:
I'm highly pleased with how this has come together. The custom form tools have been designed and ordered, and the Swiss machines are about to turn out Thumb Buttons and the Adjustable Catch Block. The validation in the Mill/Turn has been with the V-Series 17 Round to test the clearance envelope, and the 10 round case halves are about to start. Pictures very soon.
DDG Range Test Fixture:
I've been receiving DMs and emails about the Range Test Fixture. I've held off on the launch during the summer slump and have been planning to start taking orders around mid-September. If you guys are ready for them now, I'm perfectly willing to get them in the mix sooner than later.
DBMs:
The DDG Standard M5 and M5x DBMs are in the early phases of LRIP, so, like the Range Test Fixture, I can get ahead of the curve and start Pre-Orders if there's enough interest.
All the best,
MB

For the sake of the Pre-Order, I believe it's going to be around $415 with a bushing plate.
