What length barrel and powder are you going to use? My newly built 300 win mag has a 31" Krieger barrel on it and pushes a 208 hornady ELD Match at 3025 fps+-3-5 fps with 75.8 grs of h1000. Depending on powder and barrel length you could be pushing 3150+ fps. Let me know how it groups those bad boys. I might get some of those and try a hunting load.
