Looking for some one who has experience shooting a 30-06 AI. I'm looking at having my Ruger #1 RSI re-chambered into the AI. It currently is a 30-06 and I really like the rifle but would like to get a little more out of it. Should I have a new barrel made or can someone simply run a reamer in the existing barrel? It has a somewhat "tight" chamber and short throat compared to my old Rem 700 and is finicky with minimal neck growth. What I'm hoping for is to minimize neck growth with adding a few FPS to put it between standard 06 and 300 mag velocities with the shorter 20" I have a ton of 06 brass so rechambering to a 300 mag is what I want to avoid and the AI would be more "fun" and interesting to me.
