I shot a friends 444 once and it really does come back at you. Not sure if its the relatively quick burning powder as par of it but you are chunking a pretty healthy sized bullet. I would put a good pad on it but probably the best thing you could do to reduce recoil is add weight. Just some lead in the butt or one of the mercury recoil reducers the shotgun guys use. You could hollow out the forend to add some balancing weight too.
