I wouldn't worry about a muzzle break, they do make things harder on your ears and anybody that happens to be close by.
Work with the rifle, if the factory loads prove to be to much for you, then try some handholds from the bottom of the charts, or even the youth load data.
You'll probably be alright, keeping in mind this is a hunting rifle and as such shooting 5
-6 rounds at one setting will be more than will hopefully ever happen when out in the field actually hunting.
