And what does it offer that you can’t find in an existing cartridge?
I think it'll benefit from the standard chamber with correct twist, and suited to heavy bullets. About all of the other 7's in that category have to be built.
Not saying it'll change the world as we know it, but it'll do the same thing as a 300 PRC does with a 300 Win. Up until the PRC we basically had to build them and chamber them to work with the longer bullets and add faster twist barrels. The PRC's are a factory option without too much compromise.
