Looking at the list.

.222 Remington
.220 Swift
.250 Savage
.257 Roberts
.25/06
6.5x55
7x57
9.3x62
.404 Jeffery

and

.480 Ruger.

I have no idea how the latter got on that list as it so obviously doesn't fit. A handgun cartridge while all the others are firecrifles. Probably that one IS advertising. It's obviously been reintroduced.
