I am aware of the striker getting fowled to the point where it will not slide forward. About every 10 shots I pull the striker out, then twist the nipple and breech plug on my Diamond to make sure that is all behaving, and while I have it out, I wipe the striker down real good and then the striker slide area. Takes only a minute. I also learned that lesson the hard way when I pulled the trigger and it did not fire, then suddenly did.

I think for over all accuracy of a rifle, the Black Diamond XR is hard to beat. I feel it will shoot with any of them. The real draw back of the rifle is the exposed breech design and the bad fowling. Other then that the rifle will really shoot impressive groups.

Right now I am testing some .451 diameter Barnes 454 Casull 250 grain XPB Cannelured in black harvester sabots. They shoot great out of the Knight Rifles and I want to shoot them in the Diamond. These look identical to the Barnes Expander but are a lot more cost effective. They can also be pushed real hard. I think the Diamond will like them.
