Go with the WSM it is a real winner. It will never surplant the 270 win just because of the years of experience, but its superior in everyway. Reloading is a breeze. Alliants R19 is the powder that mine likes. I'm pushing 150 gr. pills at 3000 + FPS and shooting them into .75 MOA Thats a whole lot of punch in an accurate package.
