Has anyone run this configuration. I wanted to do one a year or so ago but smith talked me out of it. Telling me that I wont see much of a diffrence vs a 264 win mag. I can't get the idea out of my head. I don't care if its an absolute nightmare on the barrel. I just like the idea of a fast 6.5 for a hunting rig it would take me a long time to burn up the barrel at 20-30 rounds a season. I would like to just neck down 300wm brass and run. Good idea or bad, any info would be great
