That barrel definitely sounds like a keeper. There is one other bullet that may prove its worth in the hunting fields for the 10-14" 6.5 TCUs, but I haven't tested it sufficiently to warrant comment. That bullet: the recently-introduced 120 grain A-Max.
My very early work with it, though, does not immediately put it in the same league as the 120 grain Nosler, but like I said, my experience with it so far is relatively limited, so I will refrain from any further comment.
