I'm not going to second guess your sight picture and POA vs. POI, but with a consistent sight picture, and consistent trigger control, you should get a decent group somewhere... even if it isn't at POA.I have a S&W 422 pistol with adjustable elevation. I mainly shoot at an indoor range of about 25yds but have trouble getting good groups out there. I was wondering if there was a good rule of thumb for aiming closer to hit close to poa at 25 yds?
What he said. ...plus, make sure you've got a good grip and are concentrating on trigger control(squeeze).Start at 5 yds. Use both hands. If a rest is available, use it. Fire a ten shot string aiming at a plain black bullseye or perhaps a black square measuring maybe 2 inches. Note where your group forms. If no group forms, practice until you can shoot a good round group. Next move out to 10 yds. and repeat the process. At this point you may note a need for a sight adjustment. Make no adjustments until and not until you can shoot good consistent groups, sufficient for you to know exactly where they pistol is actually aimed/hitting. Once you have your POA=POI, then move out to 15yds. Repeat the practice routine. Keep extending the range until you are satisfied with the distance and results.
