Weatherby released a cartridge late last year, so while it is not "New", it is the first time the 6.5-300 Weatherby has been seen at SHOT.
Needless to say, it is a screamer.

Two years ago, Nosler introduced their 6.5 round called the 26 Nosler (6.5mm approx equals .26 inch)

Last year, they used the same case to create the 28 Nosler

This year at SHOT they announced the 30 Nosler.
Jay already has a thread going, so I wont duplicate that any further.
