Help with long range caliber and rifle please

i live in az. i hunt what you hunt. i also compete in f class. not sure where you are. just the practice ammo to become good enough to hit at 700- 800 would make reloading almost imperative. a lot of guns/ calibers would work. would not be light. a 7mag sendero would get you there. a 6.5-20 leup.
