Sold some guns and looking to consolidate. I have a 6.5 creedmoor, 6.5 Swede, 257 Roberts, and 223. Does it make sense to have a 30 caliber for bigger jobs? Or is there basically zero difference between 6.5 and .308 when it comes to stopping/killing ability due to modern bullet technology?

And yes i am redundant in my rifles but they have varying degrees of different tasks and sentimental attachment.
