I recently noticed that Dakota Arm's 2019 catalog no longer features the Dakota Miller single shot rifle built on the DeHaas Miller action.
I sent Dakota an email and they confirmed they have stopped making them. I own 2 Dakota Miller Classic rifles that not only exhibit beautiful workmanship but are also tack drivers. One is chambered in 7mm Rem Mag and the other in 300 Win Mag.
The M10 is lighter and more elegant. I used to own one chambered in 270. Recoil was a bit stout even with that mild caliber. It shot about 0.8-1.0 MOA with factory ammo.
The Miller's are both sub 1/2 MOA with factory Hornady ELD-X ammo.
