22 Nosler.
Seriously though a 270 is an absolute.
Would flip the Hornet, Fireball, 204, 222, 6 Rem and 260.
Leaving 22RF, 22-250, 243 and a 270. Anything bigger would be single purpose. JMO

The 270 is fine cartridge, but we all know the stigma it has on the campfire. I am afraid Ingwe will see it and I will have to come out of the closet
