You might have to adjust your loads a couple of tenths either way . But you may find out you'll become a Rem buyer after using them . I did .Found 2 boxes of rem. 7 1/2 br's today at local gun shop,last 2 they had.Went in looking for the fed 205m's myself.Got 4 different rifles that I had been using the federals in.Hoping these remington's work as good.
