With the advent of newer powders & bullets, the 270 isn't going anywhere. I've taken multiple species of game with mine. It's my go to. I think people get hung up on the energy figures too much. 1500lbs. minimum for elk, 1000lbs. minimum for deer. Honestly I think, all one needs to do is concentrate on getting the bullet to the right spot and physics will take care of the rest. I shoot 110gr. Barnes TTSX out of mine and taken game out past the 1500lb & 1000lb minimum threshold, and guess what happened? I went home with game meat from the field. Before I got my 270, I used a 243, again, was told past 250-300 yards, its not enough, well tell that to the deer that fell to the 80gr GMX bullet, past the 300 yard marker. No the 270 isn't going anywhere, anytime soon, it's just evolving into a better cartridge now with the newer powders and bullets available.
