So you are looking for a trainer, shooting steel at 1k... it won't be a hunting rifle.
You are going to hate this, but hear me out.
You want something capable that you can shoot as cheaply as possible, which means you also need a selection of inexpensive factory ammo capable of 1k. You also need an inexpensive scope that dials accurately with dependable RTZ.
Ruger American or one of the Savages seem like a reasonable platform to start. But I would choose a 6.5 Creedmoor and an SWFA or Arken scope of your choosing. And I say that being personally creedmoor adverse.
Plain and simple, what you are asking for is NOT best achieved with a 30-06.
