If you had $5K to throw at a rifle including optics, and you dont reload and want to shoot paper and steel 1000 yards.
That could be an exercise in frustration. Seen many factory rigs(TRG 42's/NightForce combo's) and customs (5k+ in price) at the 1000 yard firing line embarrass their owners with 15"+ groups.
A lot of the issue is factory loads and/or hunting grade handloads along with practice (spent primers).
An option is a T3, accurate-repeatable turret adjustments in a scope with enough power. Spend the other $3.5K on a reload set up and components, then practice.
