RE: New Cartrige?
I just recenty got a 300 WSM and love it. The WSM's are made as short action cartridges made to mimick the performance of its full length brother. The 300 Win Mag and the 300 WSM are the same and the 270 Win and the 270 WSM are the same. Its hard to beat a 30-06 like LW said but if you want something not many other people have then i would suggest a 300 WSM. I jsut got one and love it.
