10 Years ago I bought a 7mm WSM..the world seemed to be changing and time tested cartridges were "new and improved" Now Cabelas has stopped carrying ammo for the 7WSM-and I'm not sure there are any new production rifles in that caliber anymore.

So now that I am looking at a big bore rifle..am would I be going down the a similar path with one of these new Ruger/Hornady rifles?

Is there much to gain in these updated calibers?
