At least we agree that it wouldn't be a first choice caliber (lol).
270 wouldn’t be my first choice for anything but it does a lot of stuff real well. It’s certainly not too light for elk, I’ve killed around 12 and they didn’t seem to think it was too light. But yes, if I didn’t have a fun and was buying something for elk hunting, it wouldn’t be a 270. It also wouldn’t be a 6.5cm, a 308 or a 375 but they will all kill elk stone dead with little effort.
