Define 'accuracy' for us and you may get a more informative answer.

Are you talking paper targets or game?

Distances that you are planning to shoot?

Accuracy is as much the shooter as it is the rifle, bullets, scope, etc...

In most circumstances, the .270 Win is as accurate as any other cartridge. Performs well on game. Most will shoot the budget factory ammo well. I think every manufacturer has several rifle models in .270 so you have a big selection. Great cartridge in my opinion.
