You sound like me many years ago when I was building my first custom (non-competition rig).... I could not decide on the exact caliber much less the chambering for that caliber. I wound up with 22-6mm, 6x284, 25x284, 6.5x284. If I had to do it all over again, I would do the three barrel switch gun and leave out the 6.5x284. I have never even shot the 6.5 or .25 barrel. I just cannot fathom having any more fun than playing with the 22-6MM and the 6x284. The 284 case is really not that bad on barrels if you don't let them get hot and continue shooting like a machine gun (I have over 2000 rounds on mine at 3700 fps with 90 BT and it still shoots bug holes). If you are going to shoot it fast with a lot of follow up type shots, then a BR case and/or variation thereof will give you better barrel life. But, for shots on animals with cold barrels the best I could recomment is the 6x284 and 22-6mm.
For gentlemen shooting (minimal recoil to see the impacts) in a non-hunting setting, I would say the BR or the BR improved type chamberings. They are fun to shoot and you will enjoy yourself. FWIW, I am getting ready to have a new 8 twist barrel chambered in 6x284 next week so I can shoot the longer bullets (i.e., 90 sciroccos, 107 Sierras and eqivalent Bergers).
One more point...... A custom action and the customized factory actions are about the same investment. The best would be to purchase a used custom action which will usually get you under a tuned factory action. And,,,,, you will probably be much happier with the custom action.
