I have also harvested elk and moose with a .270, however I always felt I needed to restrict myself in distance and especially shooting angle. At the time my choices were basically Nosler Part. and Winchester failsafes.A few more now however I am still of the opinion if your looking at a single rifle to huntlarger thendeer sized game then you should be looking at the .284 and up calibers. Assuming you won't be reloading you should also consider cartridge choices that offer a range of bullet for possible uses. In the .284 class the 7mm rem mag is the most popular/available of the bunch. In the .308 class the 3006 sprg is the most popular, however goodavailability for the 300wm, 300wsm and 308win exist as well. Recoil might be a concern so the 300 wm & 300wsm present the most recoil of these listed. The7 RMand 3006sprg are really pretty close, though 7mm rem mag is a little sharper 7 louder which give the impression of slightly more recoil. The 308win would be the least of the bunch, though it also is the least powerful so stands to reason recoil numbers will be lower.

In terms of the 7mm rem mag it has been my all arounder choice off and on for a number of yearsI have harvested antelope to moose. Close to longrange. Normal to tough slugging conditions have been put in front of its path and it's always performed. My 7mm rem mag has basically become my deer rifle, sinceI moved in a .338wm for elk, moose & future large game(big bears, etc). For my deer hunting needsThe 7mm rem maghas always been a good fit and I know it works for larger as well (nice fallback option). I have owned 300's &3006 which were equally qualified as an all arounder, just liked the rem mag a tad moreand thus it stuck.

As far as which rifle, fit and feel are the most important thing to choosing which one you buy. Get out and shoulder as many as possible or within your budget, the list will shorten I'm sure!
