The .358Norma, was offered later in the later and inferior ZKK series, NOT in the 21/22 series.

I have sold most of my Brnos, but, owned several 21/22 series, ZG-47s and ZKKS, I have only one 21 and one ZG action left and a few custom rifles on each of these.

The Parker-Hale Hussar was on the superb ZG action and WAS factory chambered in .308Norma, I know of one re-barreled to .358NM.
