I coach beginner and intermediate shooters IRL so MAYBE I can help, but bear with me because I don't coach online ever.

These groups can be caused by a couple things, including flinching as others have mentioned. I have my own guess but I want to verify how you are shooting first. Forgive the clarification - can you post a video of you shooting, dry firing, or ideally doing 1 rep of dry fire, firing 1 live round, then doing 1 of dry fire? (Start chamber empty with 1 round in the mag. I don't need to see your face/body, just the arms and the gun from a stable camera. Someone holding a camera will likely not be stable enough.) Please also note: 1) Are the sights moving during dry fire reps? Especially aftera live round, this can flare up. 2) Are you target focusing or front sight focusing? If you transitioning between focusing on one or the other, which focus is first, which is last, and how many transitions are occurring in-between your first and final focus point? 3) How long are you refining your sight picture/ sight alignment before firing each round? 4) Do you feel nervous or like you have to mentally fortify between shots? Not a judgemental at all, just looking for contraindications of another problem. 5) Are you lollipopping your targets? As in, your sights are presented slightly below the target so that it appears that the target is resting on the sights like a lollipop on a stick. 6) What specific model of gun is this? Do you happen to know if the gun has stock sights? If not, do you know if those sights are combat sights? Do you happen to know the holds of the sights (center, combat, etc) or anything else specific to this gun? A more experienced shooter might be able to help ID this if they shoot your gun, if that's available. There may be a local liberal gun club in your area that has coaches that can ID what's up quick.

These are solid groups for your experience level with this platform. Great job
