"its your gun and you can do what you want" But if it were me I would follow a break in procedure. IMO a standard production gun does not have the polished bore as a more expensive custom rifle with a premium barrel. These barrels have minute tears in the bore/rifling from the manf process. Breaking in a barrel does not improve accuracy of the barrel directly. A bad barrel will not shoot well period. What a break in does do is "polish" these tiny imperfections (maybe lapping would be a better term). The reason you want to remove them is to reduce the amount of fouling that the barrel will collect from the bullets traveling down the bore. Less fouling (normally copper build up) means better accuracy.
My process is to clean the bore thoroughly prior to shooting. Then clean after every shot for 10 shots. Then clean again after every 3 shots for the next ten 3 shot strings. That should be sufficient and has worked for me. Out of my hunting rifles I never shoot more than 10 shots without cleaning.
Oh yeah another plus to breaking in a bore is that clean up is usually easier as the bore doesn't hold as much fouling. And the fouling that it does have has nothing to hold on to and is removed easily.
