Stalking isn't necessarily getting as close as possible. For me it's getting to a position to shoot from to ensure a humane kill, at times I have actually stalked away from.the deer to get to a better shooting platformI agree, the article was more for an example of data. I'm not saying you will get the exact same figures. As for the 300 meters, this is the "stalking directory" Sure some shots may have to be taken at those ranges but it the aim of the game is to get as close as possible. Lastly, the barrel life, both rounds shooting 150 grains are travelling at the same speed so how would one wear more than the other? Grant it, I don't own a .270 but assume you don't shoot 150g bullet so I'll take your word on that
The 270 is likely to have less barrel life than a 308 because there is more powder getting burnt in a smaller bore.
