RE: The ole .30-30???
Just use it as a back up. I use mine while driving, and while still hunting in thick woods. IF you are able to pick up deer quickly through a scope in thick stuff, leave the scope on. if not, just use the open sights. I just use a 4x on mine. I have killed.....around seven or eight deer with it maybe. from 20ft. Out to 110 yards. Great gun. Hold on to it. sometime you will need it, and then you'll be glad you have it.
