I have a 7 remmag and am getting a 7wsm when i get home. someone made a point baout all the different 7 mm's out there, and it was a very good one. if you handload the vriety of bullets out there is far superior in 7mm in wieght and type. 284 is far more popular than 277. anyway if not 270 and 7rem mag both have a huge variety of factory loads available everywhere. I handload so i go with 7mm's. I like short actions so I'm getting a 7wsm- though it'll probably never replace my 7 rem mag. Anyway look at what you really hunt and where and get the gun that'll work best for you r REAL hunting. If you might one day hunt elk, borrow the 300 win mag one of your buddies has for that 10 days or whatever. Anyway 270 isn't too small for elk or moose- but it's not really big enough either. 5.56 kills most people that get shot with it- but it's not really big enough for people you know. good luck.
