A Nova should be more than capable for your purposes. Whether you use rifled slugs in a smoothbore or saboted bullets in a rifled bbl, the results - if you do your part - will be well within minute-of-deer. Didn't mention if you'll be using any optics or not. Doing so will likely make longer shots a bit easier. Iron sights will be adequate also. For comparison, I have ghostrings on my M1 and it'll cloverleaf 3 shots @ 75yrds. Try a few different loads to see what shoots best in your particular gun. Keep in mind the shotgun is not a long-distance tackdriver.
Good luck!
