Sounds like a good battery although I've never had a 30-30 I really liked. I just can't get them to shoot for me. I do prefer the larger bores, and the 444 is a favorite. It shouldn't loosen your fillings too much, just hold the rifle firmly and pull it into your shoulder. Get or borrow a Past recoil pad or place a towel between the butt and your shoulder if you have any qualms. I won't quite say that recoil can be your friend, but I know a few guys that say it's better than coffee to get them started in the morning.
