To me it is a great round but one that is limited because of the person using the gun. It is were the recoil really starts coming in to play and more then a few cant handle it. If your not recoil shy may be one of the best overall guns for hunting.
My limit is a 300 mag for recoil and the one 338 I shot was just to much for me. The 338 does not make up for bad shots but does a great job when the shooter does his. I don't think your recoil shy so maybe a good choice but so would that 6.5 and I would take both.
For me knowing the list you want to hunt. I would load up some 200 grain or 225 and not be scared to shoot anything on your list.
This isn‘t a magnum caliber, it’s a standard caliber and the recoil is less than a 300 win mag. 200 grain would be my first choice, followed by the 225. Anything more than that I don’t see as necessary. Fantastic caliber IMHO. Have an AR10 in this chambering and it’s a beast.
