I used to be a marksman instructor and most of the time what causes this to happen is simply the shooter and it is very common ( Please don't take offense) when using a simiauto for some reason many of us have 2 cheek welds. Weld 1 is before we take the first shot and weld 2 happens after we take the first shot. Think of it as sand settling in a bucket. To test the theory you can remove your face from the stock after every shot and see if all of your shots go high. Most of the time the avid shooter will overcome this during one shooting session, once it has been pointed out to them. Give it a try, and good luck.
