I just researched this a lot and ended up buying a 270 WSM !! I whitetail hunt mostly so I really compared 140 grain bullets from Federal, Winchester, and Remington ! The 270 wsm "on paper" shoots a little flatter and has a little more energy down range !! I don't know about the real world much but @300 yards my gun has less drop than my buddy's 7 mag...........but it's not a whole lot .....probably 2" of difference !! I think he was shooting 140's like me but he may not have been............I'll have to ask him !!
Also ask him what type of round was it? It could've been the same weight but that doesn't really mean much.
