One thing that is fun, you can load 44 mag with unique and in a rifle if is a powder puff. Even H110 at max, not a big deal. Fun to shoot. Granted you are buying it for hunting not plinking.
I personnally don't find 45-70 a big deal, but I grew up on old remintgons with plastic but plates, and that is what I am still using. So put a rubber pad on 45-70, and doesn't seem any worse than 30-06 or shotgun.
