Nobody. The .17 HMR (for Hornady Magnum Rimfire), is a rimfire cartridge, not a center fire cartridge.
Anschutz, CZ-USA, Henry, Weatherby, Ruger, Remington, Marlin, Browning, Savage, and Crickett are among the list of manufacturers who manufactures .17HMR rifles, but, as with the cartridge, they are all rimfire rifles.
Ruger is one.

Read the roll mark on the rifle.
The difference is explained in the name. A rim fire rifle uses ammunition where the hammer strikes the rim of the bullet. In a center fire rifle, the hammer hits the the center of the bullet. Rim fire ammunition is usually small, like a .22, and center fire ammo is generally larger.
Any rifle that the firing pin strikes the bullet casing right in the center of the casing, causing it to discharge is called a "Center Fire Rifle." In contrast a "Rim Fire Rifle" the firing pin strikes the edge or rim of the bullet casing causing it to discharge.
The part which the bullet comes out of....
Well over 1000.

They'll work with either, and are perfectly capable of being mounted on a centrefire rifle.
If you look at the bolt face, a center fire rifle will have the firing pin located in the center of the bolt. A rimfire rifle will have the firing pin located on the outside edge of the bolt.
