Or do people just brag it’s a 1 MOA gun if they do that group once a session?
Yes. This is why thousands of videos like this exist:
There have to be ten times as many people who overestimate their abilities as those who underestimate them. Finding out you're in the latter club is the cherry on top of hunting or shooting; finding out you belong to the former group is a really horrible feeling for anyone who doesn't suck.
i changed a few basic things and in the order that helped
Glad to hear you got some better groups! Do be mindful in the process of dialing things in that even small changes can influence POI. You always hear that "Adding a bipod can change the POI on rifles because it can cause some stocks to contact the barrel." True. But even much subtler changes can effect your groups. If you sight in while wearing a winter jacket or two, your rifle's recoil impulse in the 1000th of a second after the primer ignites will be different than if you were wearing a T shirt. Just food for thought!
