Tinker thanks for the quick response. No to both your questions. I haven’t slugged the barrel but it sure looks .22 caliber and the rifle looks original and unaltered. After I posted this I read that the euro designation for the .22 hornet is 5.6 x 36R while the 5.6 x 35R is the Vierling. Very confusing topic, almost as bad as the various 8 x 57
cartridges!
