10AR brass
I think (?) he's referring to a 10mm Auto Rim case (10AR)??
If so, all we can do is keep sending requests to Starline to make them. Maybe we can wear them down; I've asked several times already.
If you're a gluton for punishment you can make them out of 41 Magnum cases with some trimming & sizing.
I made a handful (for the halibut), loaded them up & they worked fine in the 610 while it was still chambered as a 10mm Auto.
They (still have to) headspace on the case mouth (because the rim isn't the extra thickness needed), like when you shoot 10mm Autos without moonclips, but the rim allows you to extract them with the ejector.
I'll be waiting for Starline to step-up to the plate.

Now if someone would make a 10mm AR...;-).
There are LOTS of AR style rifles...
