You also have to ask, "Inaccurate compared to what?" Other guns of the same type? The same gun, before and after "tuning" it (glass-bedding the action, slicking up the trigger, etc.)?
Accuracy means one thing to a benchrest shooter who's measuring it in fractions of MOA (minute of angle)... but it'll mean something else to a person whose only rifle is a Mini-14, and who has just shot a decent bolt-action for the first time: "Wow! the holes are all in the middle of the pie plate!" Some gun designs are inherently more accurate than others.
Never let anything mechanical know you're in a hurry.
