Actually probably should thank you for bringing up those problems and they were problems. But:

If you would go back and read the later posts I think you would find that the individual told us that he was loading the primer wrong and then crushing it in the primer pocket. He did not know that were rails in the nose of the bolt the primer was suppose to go in. And of course that would also not allow the both to close. Once in awhile operator error needs to be considered.

I do not remember anyone saying that got the wrong bolt/bp so you must have read that one someplace else, so I am unable to comment on that one. But it does seem like it would be awful tough to do since the bolts are different for the Extreme and the Mountaineer.

The only thing I remember is Knight sending a new bolt and BP to the individual that was not placing the primer in the bolt correctly, hoping that would cure the problem he was reporting.

+ all three of these problems were fixed when the poster was shown how to load primers in a Mountaineer... Had it been an Extreme it would have worked great.

I would be my guess they will start showing up as the folks that have them start shooting them. Of course then you have to wonder how many of the ones that have em, belong to one of these forums???
