Both the clear plastic loading tray covers of my Autoprime XR have now shed their retaining clips. Thought it might have been easy to obtain replacements, but oh no - this is what you have to buy if you wish to replace the loading tray components.

The "upgrade" looks pretty naff to me, but of particular concern is the instruction on the back of the packet which states that Federal Large Primers (Rifle and Pistol) should be loaded singly. The inference being that if one goes off it will set the rest of the contents of the tray off. I suppose that's understandable, but it's the first time that I've seen Federal primers singled out for special handling. Does anyone know why Federal primers should be considered particularly risky?
