Good to hear you got some range time in, that is never a bad thing. As for your shot's being off, you need to find your shooting position. Make sure you have a proper, balanced stance. Steady your breathing. I aim with both eyes open. Helps me to see the sights and the target. Plus being left eye dominant and right handed, using one eyes really screws me up. So check which eye dominant you are and adjust. Don't hold your breath, this will make you shake. The best time to squeeze the trigger, not jerk it, is right when you exhale. There is a natural pause in your breath and that is when you are the most steady. Like someone said, tape yourself if you can, or have a spotter watch you to coach. I'm usually off with other people's firearms until I've shot a little with them. Different ergonomics, sights and trigger pulls will throw anyone off. It's interesting you say you were dead on with the .22 but off with the larger calibers. Sounds like you are anticipating the shots or your grip/stance needs improvement. With the .22 there is less recoil and noise so you might be relaxing and not trying to over control the firearm. Just my .02.
