What size groups are you getting.
And are you capable of shooting "good" groups or not?
Check your hardware and make sure everything is tight. If you have an extra scope you can swap it out and see if that changes anything.
Have realistic expectations as well. If it's shooting 6" groups there's a problem, either with the set up or the shooter.
If it's shooting 2" groups, that might be just what the rifle is capable of. That could be improved with some minor work to the rifle.
if it's shooting 1.5" or less then I would call it good.
Guess it depends on what your expectations are vs what the actual groups are measuring.
