Pacecars, you had my dream 9.3X62 by the sounds of it in the Model 21-22 Brno you had, only trouble with the 9.3X62 in a light rifle is the recoil, it can be rough & a eye brow cutter in the light weights with heavy loads & the 9.3 can be very powerful, it does the same work as a .375 H&H no trouble !

I have a Schoenauer a little like yours in 7X64 (wish it was 30/06) it is a great caliber & super accurate, if you use the rifle a bit you might find that working the bolt in a hurry might take some getting used to !
