.270 Win ?? well... the way I see it, it's not the best Deer and Elk popper out there for sure, but'..., it'll do the job until the best one comes along. Whether you're shooting a 100gr or 150gr it's a sold Deer rifle, on Elk the 150gr. is proven it's worth over and over again and it's been doing a pretty good job since 1925 I think the caliber was good enough that Roy Weatherby brought out his .270 Wby Mag 1943 and from what can be found it's one of Roy's all-time favorite cartridge calibers. Is it the best? who knows, but... it sure has some staying power as older cartridges go. Cheers!
