The 270 Wby kills elk fine, just place that bullet right in the boiler room double lung shot, now that 270 Wby is about as close to the 7 Remington Mag as you can get, a lot of guys use the 7 on elk every year. By the way my dad only used the 270 Winchester 130 grain bullet exclusivly on his elk, thats right only Sierra bullets. He was one cool shot.
