I have been a big fan of the 270WSM for a long time. My savage SA chambered in 270WSM has taken a bunch of game and its been laser gun accurate. In all honesty, I am really not sure how much of an upgrade the Western is over the WSM. I've shot the 150 Nosler Accubond LR out of my WSM with good accuracy. The ballistics difference in even the 175s out of a Western and 150s out of a WSM is negligible.
As much as the hype died down in the WSMs over the last decade or so, I would fear the 6.8 Western is likely to fade into obscurity.
Now, if Hornady had been behind it, and called it the 6.8PRC or 6.8ASM or some other catchy 3 letter tag, we'd all be talking about how its the best thing to come along in decades. LOL
