one huge advantage of the new 300wsm is that it is chambered in all modern rifles...no down loading of factory ammo for saftey reasons in old rifles like so many calibers today.
I own a Mod 70 300wsm SS though I handload so I bought 5 boxes of Winchester 180 gr factory ammo on sale to get the brass . I have a Burris Fullfield II 4-14x42 mounted with ballistic plex. off bags @100 yds with that factory ammo I am well under 1" for 5 shots everyday, all day if I wanted.
I do not find the recoil much more sever than my '06 with 165 gr BTSP handloads...but everything bites more from a bench....how about the recoil from a 3" 12 ga slug off of bags.WOW it's alot worse than my 300WSM
