With a budget of 10,000 +/- 2,000 you could have 3 custom rifles
built and 1 good Nightforce scope to interchange between them.
Build yourself a flat shooting small game rifle for coyotes/deer and such. Something in a 6.5 or 7mm.
Then build yourself a big caliber for elk and moose in a carry rig, in a 338 cal.
There are way to many options to list for a budget like that.
