8,2 x 50R?

I have found these photos in www.municion.org. It looks like a current 8 x 50R Austrian Mannlicher, but the headstamp says 8,2 x 50. The headstamp looks like Hirtenberger. Any idea?

It is the same as the 8 x 50R Mannlicher ,they change the name a little to separate it from the military production
