Yes, the Loadmaster and Dillon 1050 are the only two presses that I know of that do this.
You don't need "feel" as the primer is seated to an exact depth. Just turns out to be a better idea if you have a swage station before priming, like the 1050.
Look at the area where the excess chain for the powder measure reset is hanging in the photo below.
The upside down bolt screwed into the top of the press contacts the rocker arm below mounted to the ram. When the two make contact the rocker pushes an anvil up seating a primer in the case. If you want them deeper you thread the bolt lower.
