Who produces a rifle chambred in .30-30 winchester?

I assume hunter you mean "other than" a lever action ?? If so the only ones I know of (and I know very little...) are single shot by H&R (Handi Rifle) and Rossi (Wizzard)

 

rossi, henri,winchester are all that come to mind...you can get a custom build in any caliber

 

Wincher made the model 54 which was a flop because people preferred the more powerful cartridges that they offered
In addition, rimmed cartridges typically don't feed well with the box magazines normally found on bolt-action rifles Other examples of bolt action rifles offered in .30-30 Winchester are the Stevens Model 325, the Savage Model 340, the Springfield/Savage 840, and the Remington 788.

 

I am of the opinion that the Marlin 336 is the best lever action in 30-30 Winchester.
