Congratulations on the beautiful rifle. I was in the running for a while, but other lots soon took priority. I wondered about the caliber marking myself. My best guess is perhaps it is an attempt to denote bore diameter. There was a .223 Hornet or K Hornet recently and I suspect it was the smith's way of letting folks know it was a rimfire diameter barrel. Please share the link for others. I know they will appreciate it.

For Mike, it isn't a 219 Savage.

It ain't ignorance that does the most damage, it's knowing so derned much that ain't so! J. Billings
