Almost any standard cartridge will work out to 1000yds.
Amongst the more popular are .223.5.56Nato. 6.5x55mm Swede, 6.5mmx284, .260Rem, 7mmx57 Mauser, 7mm Mag, .308/7.62Nato, .30-06, and .300Win Mag
There are other cartridges that are popular in other parts of the world. Military rounds tend to be popular. In part that is because there is still a lot of surplus ammo.
As I said any of those cartridges and more will do fine at 1000yds. The main difference is cost. The 5.56 and 7.62 are relatively the least expensive, but quality target rounds will be pricey no matter what you shoot.
Learning to load your own ammo is a very good idea for serious target shooters.
More important than the cartridge is the rifle you shoot it out of. You can spend a truck load of money on a custom rifle or a relatively little amount on a milsurp.
If you pick a well made rifle that fits you well your well on your way.
