.257 for short or intermediate-length actions and .25/06 for long ones would be my choice if I ever go down that road again.
That about sums it up for me too; .257 Rob is an intermediate length action cartridge, so fewer rifles put there that are “perfect” and need to customize is there. On the other hand they can function acceptably through a short such as the Kimber 84M.
Long is 06 and there are lots of good factory rifles available in that fine cartridge so less need to go custom.
