It's all in the eye of the beholder...... have yet to see a definition.....
It seems I end up with oddballs as my keepers too or wish I had a few I got rid of back again. I only have two oddballs currently, a 348 and 307 win but I had a 356 win, 308 Norma Mag and I cannot recall now it's been so many years and I didn't know guns much back then but I had some kind of a Remington pump with a tube magazine that was twisted like a drill bit and was some kind of 25 cal? If memory serves there was a brass headstamp in the side of the receiver with the calibre on it?
My odd ball is a 375/06. Had the gun made up and got dies. Shoots great, is just below a 375 in speed and ft/pd's. My moose gun is a 338/06. Love that calibur and do not consider it a odd ball.
This discussion reminds me of college music snobs trying to cone up with te most obscure band ever to prove how cool they are.
If someone else likes it and uses it, it's no longer hip. ......
While I wouldn't call them oddball, I've preferred European cartridges for decades now. I've had the vanilla cartridges already. The whole deal was to have something that not many others had, the hunt for hard to find components (usually finding these at gun shows) , and finding load data that either had to be extrapolated from European sources (using powder equivalents and similar burn rates) or found in publications like Handloader or Cartridges of the World etc. Just made everything that much more interesting. Keep in mind that most of this 'hunting' was in the mid - late 80's and the 90's.
As for the 'oddball' cartridges: 6.5 x 55, 7 x 57, 7 x 57R, 8 x 57JS, 8 x 64S, 8 x 68S, 9.3 x 57, 9.3 x 62, 9.3 x 64, 9.3 x 74R and the 11.15 x 60R.
