I haven't compared the magnums but from all the reading I've done, it seems a 300WSM can match a 300WM and the same for the 7mm with a 2" shorter barrel. No big surprise there as the fatter case should be a bit more effcient and truthfully, the loss of velocity per inch of barrel in all cartridges isn't that significant. It's not hard to believe that the WSM can make up 50fps...at least for me.

this explains the reason for the marketing of the WSM's and if anyone can't understand or beleive this , its because you have a "personel bias" and can"t except change..lol...in other words let go of your 30-06 or 270 win and get NEW !!!!!!!!!!!!!!
