There are some good articles on paper tuning your bow on the internet. Also take time to get closer groups, at 20 then 25 ect. we try for closer groups. Have you lined up your arrow with a square? Are you holding at the same point?
really need more information to help much
Don't take this the wrong way, but before everyone jumps on the bow, how is your form? Do you have a good anchor? How long have you been shooting? Etc.
My first thought was that you were shooting a short axle to axle bow that you are having trouble holding steady at longer ranges. If that is the case. A stabilizer will help with that. What kind of bow are you shooting?

Well shooting a 4 inch group at 20 isnt actually that good. I would shoot through paper. My guess is bow is out of tune, or you are getting fletch contact.
Check your bow tuning
You can try paper tuning but if the problem is your form, meaning you are toqueing the bow or jerking/punching the shot, then paper tuning won't tell you much. Try walk back tuning for center shot or bare shaft tuning for nock height.
With an old bow you need to check the timing as well. If shooting groups you need to slowly extend our range in the beginning, don't overdo it by jumping out to 40 yards if you are shooting 4 inch groups at 20 yards. Set a goal of not moving to longer yardages until 4 out of 5 arrows are touching or something like that.
Good luck
Practice more. Sure, make sure your bow is tuned, but if you shoot what you think are good groups at 20 yards and lousy ones at 35, you need more long range practice. If you want to be good at 40, practice at 60.
