Less accurate might be an incorrect / misleading way of asking this question. It might be better framed as - is it generally more difficult to tighten up groupings with larger Calibre rounds compared to smaller calibres?? Say, If you had exact same rifles, nil wind, shooting from a bench with same scopes etc - Say a .22 something vs .3 something...OR is the shooter / recoil the main variable and if you control that, accuracy should theoretically be exactly the same?

If it were bedded in a Benchrest stock and shot off a Farley rest it could do better. It also is difficult to get really low SD and ES numbers from it as you are burning over 100 grains of powder. It is not to say that the caliber is not inherently accurate, just hard to realise its potential.
In the main 6mm rule the roost regarding accuracy over most distances, easy to shoot and load for.

As distance increases the variations in velocity will compound into larger variations of impact height. If enough work is done to eliminate the multitude of variables in rifle / cartridge then single digit ES & SD's should be possible but it becomes a game of diminishing returns. Here's a thought, is the 6.5mm which is deemed one of the more accurate calibers because of size or because, due to popularity there's a better choice of projectiles? If the beard grooming twat-knot bunch were suddenly driven to moisture by the 375 H&H would we see a bigger variety of high BC target projectiles?
I have managed to achieve the holy grail of low numbers in a large cartridge (2nd Row) and many smaller ones...This is one of my go to loads for 1000yd competition Data was captured from a 5 shot string using a Lab Radar and I've managed to repeat it more then once. Even with a 10 shot string I was still in single digits for ES & SD
