I realy don't see the difrence of these "Super Short Magnums",I mean other than a lighter gun or short action is that enough to keep them around?
I look at the 243 WSSM and see the 6mm Rem performance.The .223 WSSM has 22-250 preformance all over it.

Why did Winchester put a .25 cal cartrige in the line up,if the wanted to make sparks fly,why not load it on the WSM casing,and make a cartrige that has Magnum potential!
I'm just arguing for sake of arguing on this,I mean I have two 300 WSM and think they are the cat's meow.
I was just hoping they would have made a 25 WSM not a 25 WSSM Super Dud.
