The new sendero and the old ones all bed the same , via an aluminum bedding block , having it bedded might help with accuracy as it might not , i reccommend bedding all rifles cause its not that hard for the average guy to do and if it doesen't help with accuracy thats just one more piece of the puzzle that you don't have to worry about. The rifles with the bedding bloack like this ganeraly just get "skim" bedded meaning theirs not a thick amout of bedding just enough to make the contact skin tight.
Generaly , a factory gun will just about always benifit from a bedding job and a good recrown that cut true to the bore.
