It's all hundred year old technology. A metallic case, primer, bullet, and smokeless powder. Regardless of the shape of the case it is still the same technology.
Different cartridges offer individual people different things that they like or dislike.
I much prefer the case design of the WSM's over the belted magnums. Personally I would like to see a standard (30-06) length cartridge based on a lengthened WSM. But that won't happen cause it would really be a direct replacement for the 300 Win mag. and Winchester certainly doesn't want that.
BK, no problem.
