Mr. Smith,
When I started shooting LR, I started with a Savage tac 20" in .308. The rifle was not and still is not a true 1000m shooter, but it shot much better than I did at that range. Since then, my skills have grown greatly and I've added some real shooters to my collection. If I had started out with a $2k+ rifle, I don't think I would have seen the difference on paper. There are a lot of things going on between the rifle and target that impact accuracy more than the difference between a 1moa and 0.3moa rifle. If I were to start over and needed a rifle, I would get a used 700 police chambered in a rd that does not have too much bite on the back end; then I'ld mount a quality (+/- $400) scope, one piece 20moa rail and a good set of rings. A good (mid $ range) set up should outshoot you for a pretty long while. Also, that 20" Savage that I've had for 10+ yrs is my 'go to' rifle for deer, crows, yotes and just about anything else that needs shooting out to about 500 yds.
IMVHO, after you put a couple thousand rds down range, you'll probably be shooting as good as the mid price setup.
