I have a .22 Norica Mod 73 I bought back in the early 80's. It has been sat in my loft for the last 25 years or so but I've pulled it apart cleaned it up and it works beautifully with the 4 x 32 scope I have fitted. What I can't find is any information on the spec. It does appear to be fairly powerful and I'm a little worried it might be close to the 12 lb/ft limit. Does anybody know anything about these ?
