Hello HaYen,The bolt head you list is for a magnum size cartridge
head.It is a replacement head for the large shank wsm size action.it has a slot cut in the head and a ejector in another slot cut in the action.it is an ok setup for the wsm's but only ok.savage has a couple of new tricks including the center feed,
and a new style bolt head but no crf in a standard bolt face.
Hope this answered your Question.Vic
