Here are my suggestions.
1: look for a used Sendero in 300 win mag for your starter rifle.
2: If you hand load, load some 215 Bergers with H-1000. If you have no access to hand loading look for some factory ammo with a large high BC bullet. Like a 190 SMK or bigger.
3: install a good rail base and rings like Nightforce and a scope with a target turret in 1/4 (.25) moa A zeiss conquest would be excellent at the lower end of the price range I would use.
4: Download the "shooter" app to your phone
5: buy a used Leica 1200 CRF or used 1600 CRF
6: Watch for a kestrel
2500 or 3500
7: install a Harris 9~13 swivel bipod.
This is what I call a minimum requirement for 1000 yard shooting / hunting. I know your area well and know what you will be hunting. This combo will work.
Later when you are ready to spend a little more $ have the trigger tuned or replace it with a Timney, install a JP precision brake and have the rifle bedded in the action and front lug area.
I have put together many of these for friends. This combo flat works. Although this is still not an inexpensive venture, all these products are quality and very marketable if you ever decide to bail out.
Hope this helps
