I'm thinking you already have a good gun that you're used to shooting so why trade it for a different one? If you can find some hot load for it with a lighter bullet it should be able to shoot fast and flat and still kill any big game you put your crosshairs on.

I don't know what bullet sizes you can get and limiting your options to factory rounds will limit that option but if you have a friend that reloads maybe buy all the gear specific to your caliber and have him/her show you how to do it and then borrow his gear to reload some shells.

Cripes, I couldn't stand it...just dug out my Nosler manual...you can load up either a 200g Balistic Tip or 210g Partition to over 3,000 fps for that rifle. I see no advantage to trading it in unless you just *need* a new rifle. I would suggest doing what you think works best for you in this situation. You know enough of the facts to decide probably now.
