7mm Rem Mag factory ammo

[Randomized]

Hi guys, I'm going out to do a shooting course where we will be shooting out to about 1300m. I will be shooting factory ammo on the course out of a Remington 700 sendero sf II in 7mm Rem mag. I was wondering if you guys could shed some light on some good factory ammo options to use/try?

Thanks

Hornady "precision hunter" should do the trick. Eldx bullets with a great BC.
