Depends on calibre
Depends on calibre
Both the Jackal and the AA sidelevers (both made by NSP) were offered in both .177" and .22", just not all models.
The auto load ones only came in .22". I think the short-barrelled models were all .22" too, but stand to be corrected. Some of the long-barreled ones may only have been offered in .22", but others came in both main calibres. Given prevailing tastes at the time, probably 9 out of 10 (at least) NSP sidelevers were .22"s. The Camargue was also offered in 1985 in .20", as well as .177" and .22".
