Shadow2, do you have really big hands? As 1Sow said, I would start with seated bench resting at a table with sand bags, a rest, etc. Arms fully extended, 2-hand grip in a natural seated position then shoot at a distance of 15-20' to establish POA/POI. You start at a short distance to establish your sights. Take a full breath, let half of it out then hold it and concentrate on a slow even-pressure trigger press. Take the shot within 10 seconds or start over. Have someone else repeat the same drill with your gun and see if your POIs are similar. Typically your shots will break high left if you are applying more pressure with the heel of your palm to the grip.
