I just got hold of an old German .22 Hornet and have been looking up reloading info for it. One of my very old manuals has a note that pre-1940's .22 Hornets have a barrel size of 0.223" rather than the modern 0.224" that normal .22 projectiles are produced for. I've never heard this before - has anyone had an issue with loading for older .22 hornets?
