Yes Dick, they are rather expensive and are custom made.
Where else are you going to find 58 rimfire? I came to the end of the internet finding only one company that could manufacture theses case's.
Unless I missed another company the Piper must be paid lol!!
Couldn't even find empty cases.
Other custom cases are much lower as is my Martini Henry but then again many more manufacture that brass. I could make it myself but quicker to just buy it and not get the migraine.
