Gale McMillan has long been outspoken as saying barrel break-in a waste of time.... So does that mean that your barrel break-in, wasn't a barrel break-in, and you just started shooting??
This isn't meant to rain on your parade, but a re-assesment of what you "should expect from this gun".
You didn't buy a hand-lapped, precision assembled by craftsman, gun. You bought a mass production button rifled gun, that is(in my lookings last night on several sites) the cheapest bolt gun available. Your scope, also does not have the best reputation for passing any box tests....
So considering that you spent substantially less than MOST alternatives, why are you expecting what you didn't pay for? You should be elated if it is a tack driver, and unsurprised when it isn't.
My 25-06 didn't have the smoothest bore known to man, and refused to shoot Factory fusion ammo at all.
I currently have something like 4-500 rounds down the pipe, and the barrel has come a long way. I also found in reloading that it has a VERY short throat. That seemed to cause issues with factory ammo... When I started reloading, and seated the bullets appropriately, then it started to group quite well.
