I've found the 150gr smk to be very good and the 162 eld x.
You can push the 150 quite fast, should still be easily super sonic at 1000.
This is ballistic app theory though, I haven't done it myself yet.
Accuracy wise, my Remington 700 Varmimt, nothing special, 1 / 9.5 twist I believe , shoots well with both above bullets.
