Nothing wrong with a 6.5-284. It moves 130 at about 3000 give or take. For a BG hunting rifle I am more concerned about the fit, size, and function than the cartridge. For me a perfect general purpose rifle moves a 130-150 at 2950-3100. Flat shooting, manageable recoil, light weight, and reasonable size. Pick a suitable bullet, it does the real work. Bore between .26 & .30. If more is needed then start with a .375.
Mostly the super large cases are there just to sell more stuff to guys who want to spend money trying to find performance. A 280 long throated with high VLD bullets will reach way out for a good shooter. I used one for many years and on then on a trip couldn’t find ammo to make it go bang so went to a 270 and gave up about 3%.
