Hi all, I address this to those of you who have SHOT both these cartridges. Given that the WSM case is more efficient,i.e. you get similar velocities by burning less powder, other issues that I'm sorting out are:- 1) Is there any appreciable difference in felt recoil? 2) Is there any appreciable difference in accuracy? 3) Is there a difference in case and barrel life given that the WSM operates at higher pressure? I don't own a rifle in either of these cartridges so the "Is it worth switching?" question doesn't arise. All experienced advice is greatly appreciated.
