my own -opinion- is that it doesn't really matter. if it's raining out i prefer to hunt with my stainless and plastic tikka. but that doesn't mean i'm not out in crappy weather with my blued and wood rifles. regardless, i get home, i wipe it down, stick it somewhere where it's going to dry quicker vs leave it in a soggy case. cerakote would be a nice touch, but i'm cheap and not going to pay more just for that feature. i'm also left handed so i'm limited in what i can get so finish isn't high on the list, it's all about LH and caliber for me.
i like synthetic stock and blued metal...so i can spray paint it if i get the hankerin and not feel bad about ruining a nice rifle ha
