Just found this discussion. The .270/Ontario thing has bewildered me as well. I did some digging. Here's what I found:
decription 7X57 Mauser; source Wikipedia.
The 7x57mm cartridge, also known as the 7 mm Mauser, 7x57mm Mauser, 7 mm Spanish Mauser in the USA and
.275 Rigby in the United Kingdom, was developed by Paul Mauser of the Mauser company in 1892
Many sporting rifles in this calibre were made by British riflemakers, among whom John Rigby was prominent; and,
catering for the British preference for calibres to be designated in inches, Rigby called this chambering the .275 Rigby,
after the measurement of a 7 mm rifle's bore across the lands.
Key words of note: British, preference, across the lands.
Most of us know the history of Canada and realize this British influence of laws, etc...
I only suggest, that this is where the .275 thing originated. The core intent has probably been lost and now the .277 bullet is of questionable use depending the interpretation of the regulation by whoever. I'm not sure what leg you'd have left to stand on in an Ontario court of law if a person presented this info.
I did a quick look into other similar discussions and did not see this info mentioned.
