To the original poster;

I have 2 6.5 Creedmoors....One a Ruger 77 Target, and the other an All-Weather Hawkeye that I switched out the plastic stock for a laminate one.

The Creedmoor would be a viable choice for what you are looking for.....its 140gr has more remaining energy, and a flatter trajectory, at 1000yds than a 300 win mag shooting a match 190gr bullet.
That being said...if you are proficient enough to make a 1000yd
kill shot on game; more power to you.
600yds is about my max for game, and I don't get to shoot longer than that enough to be confident with shooting anything beyond that.
One other note...both of my rifles are the most accurate bolt actions I have ever shot straight from the factory.
Good luck in your search,
johnny
