I just went to Hornady's website and the numbers might surprise a lot of you.
Now , I realize this is one ammo company and a two load comparison but get this..
7mm 162gr at 2940fps...energy @ 400 yards....1822 ft lbs..trajectory minus 19.50"
300 Win 180 at 2960fps...energy @ 400 yards...1823 ft lbs..trajectory minus 20.50".....
looks like a dead heat....
I can see my 300 getting rebarreled to 257 Wtby...or maybe 7STW....
