I'm dealing with these same issues. Fully agree that the copper bullets are changing the rules.
For a handloader, also think it worth looking at less than max loads under medium or lighter weight Partitions, so long as good accuracy is there.
Other solutions I'm working on are found in older, often overlooked cartridges like the 300 Savage and 257 Roberts. Same with calibers made out of the 308 case.
Combine these with an older, full sized rifle, like a walnut stocked Rem 700, Ruger 77, or Win 70, along with a Supercell or Limbsaver, and recoil becomes minimal, yet can deliver a pretty lethal bullet to just the right spot.
The curmudgeon in me refuses to look at 6.5's. Well, maybe a 260. Rational, eh?
