Absent external influences, bullet flight is basically linear.
Meaning, whatever the rifle, ammunition absent shooter error can deliver at 100 yards will be multiplied by whatever factor of the distance involved- provided, of course, that all the factors affecting it- gravity and wind, and to a lesser extent things like temp and humidity are compensated for correctly.
Like Brian said, depends on what your expectations are.
As a very general rule of thumb, if it can't shoot minute of angle (1" at 100) it would be unsuitable for any sort of longer range shooting. Again, that's the rifle, and not what the shooter is capable of doing.
