If you look at the 1000 yard benchrest competitions and 1000 yard F-Class competitions, the majority are being won by 6mm and 6.5 mm based cartridges. One of the winningest 1000 yard competitors these days, David Tubb, is using the 6mm XC cartridge. The 6mm BR cartridge still dominates 1000 yard benchrest competition, and the 6mm/284 cartridge is the dominant 1000 yard F-class cartridge.
1000 yard Palma is dominated by the 308 Winchester with 155 grain bullets. The difference between Palma and the other two disciplines is that Palma requires iron sights and the other two allow optical sights.
The other long range discipline is NRA Highpower Match where the long range is 600 yards. Some highpower matches are conducted at 1000 yards on the long range leg. There are two divisions in Highpower: Service Rifle and Match Rifle. Most of the time you see 30-06, 308 Win, and 223 Rem/5.56x45. These days, Highpower matches are dominated by 223 with heavy bullets from fast twist barrels.
It is very hard to be competitive with larger cartridges than these. The recoil of larger cartridges takes its toll. In general, you want to shoot the cartridge that hands you the least amount of collective recoil in order to win.
