I'm a little late to the party but here it goes. Its hard to beat an Xbullet on game. With that being said of the 5 different 6.5s I've owned, I haven't been able to get them to shoot. A cooper 260 shoots 130 accubonds, cooper 6.5 creedmoor shoots 143 eldx, MOA 26 nosler finally wanted to shoot 140vlds, 264 win 140 vlds and cooper 6.5x284 140 vlds. I would blink an eye at killing talking elk with any bullet over 125 grains out of any 6.5 and all of the above mentioned have killed elk with the exception of the 260 without any issue.
