It sounds like you have all the parts to make it go bang and off the top of my pointed little head I can't think of anything else you might need to set the rifle up.
The caliber is, as you mentioned, quite new. Loading data might yet be developmental but I have heard that cartridge is a great long range shooter, as is the 260 Remington and the 6.5 Swede.
I'm not sure what you want to hunt with it but I'm certain it would be adequate for whitetail. Mikey.
