Not to mention that the case on the 1889 version used a case that was 2 millimeters SHORTER than the 1911 version.
Sorry, but the 7.5x55 Schmidt-Rubin doesn't qualify. If the Swiss were still using the 7.5x53, then yes, I'd say it qualifies.
Different case, different bullet, different chamber = NOT the same cartridge.
It looks like it's still down to whether or not it's the .303 British or the 7.62x54R.
The 1888 Commission Mauser was chambered for the 7.92x57 Mauser cartridge, but used the .318 bullet, not the 1905 version with the .323 bullet.
Because of that, I'd have to disqualify the 7.92 Mauser.
As for elephants, there's a herd of elephants very near to where I live, so your spray isn't working.
On a similarly light note, for some time I told people that I drink Gin & Tonics in the summer to ward off malaria, and that it must work really well because there's no malaria anywhere in the Washington, DC, metro area.
Then, two summers ago, two teenagers in the county next to mine were diagnosed with malaria...
So much for the wide-net medicinal aspects. Now I just drink G&Ts because I like them....
