I like the unusual. In my collection there are:
10.75x68
375Flanged Nitro Express 2 1/2;
8x57 built by Husqvarna on a civilian variation of the M38 action;
6.5x ???? (Should be 53R but someone has reamed the chamber longer but with more taper);
6.5x57R;
5mm Remington Rimfire Magnum - getting ammunition for this in Australia is next to impossible!!!

Not a 308W nor a 243W to be seen. Not that there is anything wrong with them, in fact they are wonderful cartridges but .....

Merry Christmas,
