Youdidn't thinkI hadall of that useless information in my head did you?

It's called ammoguide.com

Oh OK. You're not a show off. You're a cheater.

Yes, there are a few. Like 4mm,.12", .14", .465", .475", .50", .510", .550", .577", .600, 16 bore, .700", 12 bore, 10 bore, 8 bore, 4 bore, 2 bore, and this is just RIFLES designed to be fired from the shoulder. No shotguns listed here.....

IF you want cartridges, get yourself a copy of Cartridges of the World. Even that volume has quite a few designsmissing-you just CAN'T list them all, particularly if you include experimental designs!

I note the forkhorn OX, who started this all, has not deigned to return to the scene of his crime.........

.243
nothing else matters.

LOL...I wondered how long that would take!

A couple of bigger guns that are ofcourse rifled that seem to have been over looked;
5.45,11,12,12.7,20,25,30,40,60,90,105,125,155,175m m
3,5,6,8,12,16,20,24 inch
Did you hit the .366
Muzzle loaders 54,58,62,64,68,72,75,76,78,82,84.
Pretty sure I missed a few metrics that don't swap to decimals directly or commonly

How about all of the calibers, and the associated brands that still make that caliber? I want just one of everything
