For a hunting style bullet I would also consider the 150 grain 7mm Swift Scirocco - it has a very high BC and has performed well for us on game. ALso good very good accuracy, some groups going under 0.5". I must admit that we have never shot an animal at real long range with the 7mm, but we killed some bears out to 200 with excellent bullet performance.
I have shot the .30 Scirocco (165 & 180) to 500 on game with excellent results. We recovered a bunch of bullets from wild hogs shot out to 500 with over 80% retension and very uniform mushrooming. Have also had great accuracy with the .30's.
Barnes also makes an interesting .30 cal match grade 168 "X" bullet that would meet accuracy requirement out to 1000, not sure how it would perform out there. We shot a bunch of them out to 1000 on targets, shot under 1 moa all the way with the .308 Win.
Last summer we shot some factory hunting bullets out to 1000 in 100 yard increments and they were stable and surprisingly accurate. Used Failsafes, Power Points and Ballistic Silvertips. Shooting was with the .300 WSM
and a .300 Win. mag.
No doubt there are other good bullets to consider, these are what I have experience with.
