If you purchase the 270 with a 24" barrel you will be giving up very little if anything to the WSM. The 270wsm will have faster recoil which in a very light gun(Kimber 8400 or Browning Abolt) could affect some shooters. I disagree with the poster that said the 270wsm wasn't selling well. I am betting it is the top seller or right next to the 300 wsm in spite of coming out a few years later.
