I just put a kit on mine and it is exactly like the Savage ML with the primer going onto the nose of the bolt and completely enclosed when bolt is shut. It is more expensive but a good version compared to the one with vent holes around the side of the breech plug where the primer goes. That one has lots of blow back. I have shot this one several times today and seems to work well with BH 209. Will be glad to get you name if you wish.
