I finally got my Chrony, and my 300 Weatherby is pushing a 208 Amax right at 3000 fps with 78grns of 7828. Which is sorta in the middle of my load work up, it should be easy on the brass and barrel. I have no reserve on taking this to 1000 yards, especially since I do it with30-06 regularly. Im going to Thunder Valley shooting range in Coshocton County Ohio Monday to try a mile. I just hope its enough velocity to do it. The 300 Win Mag guys up there are saying its enough....we'll see.
