I embraced 300 magnums in about 1992 and have mostly hunted with them ever since. Mostly 300 RUM and Win Mag, but also several years with the WSM.
The 300 WSM is very accurate and in the real world at average hunting ranges it works just as well as the other two I've mentioned. Despite the hype the recoil is the same as the 300 win mag in my opinion. One plus for the WSM is you don't have to deal with belted cases and the sloppy chambers belted cases often have.
With all this said I am now 46 and have watched my son pound the heck out of deer, antelope and elk with a 7mm-08 using the 120gr TTSX. I think If starting over a cartridge in that neighborhood is as good a choice as any.
