I did indeed hunt mine in the white. But it was good weather and only turned out to be a one day hunt. Before the next season I had it rust blued.
I have since hunted it in all kinds of bad weather. Inland and coastal. I’ve never had a spot if rust on it. I keep it cleaned and protected. I wipe it down liberally before the season with paste wax. It seems to do a fine job of protecting the finish.
Cerakoting is a good option for a CM barrel if you want some good protection. I have several rifle so treated.
My 400 has been my all time favorite project and remains my favorite big game rifle.
