No offense, but did these experts actually do a chamber cast and slug the bore? There are a pile of chamberings for rolling blocks that are REALLY
close to 45-70 dimensions. Darned near every country in the world used
the rolling block, and each one had their own caliber.
That's just for the Remington produced guns. I'm not all that sure that
yours is a Remington. There are gazillions of the darned things out there
that are authorized (licensed) and un-authorized copies. The near total
lack of markings on yours is interesting----No manufacturer name, no
serial number, no country crest, no proof marks?
