Welcome to the forum, if you cant find the answer around here it does not exist!
I am also a new guy but I have 3 rifles that are cf actions with dbm's. I could be wrong, but I believe that the sf actions have the box attached to the action itself, where as the center feed does not. So you want to get a cf action if you want to convert to detachable box mag at some point. I hope this helps, otherwise someone will correct me if I am wrong.
