The 7 Rogue is out new wildcat that is based on a necked down, long neck, blown out 300WM case. It runs 180 Bergers at 3180 in a 27" barrel with a comfortable load, over 3200 with top end max loads. Will be releasing it out to customers towards the end of the year after we run it for awhile. I thought about the RUM case, but its to much volume for the 7mm. It will work with slow powders like US869, but I wanted something that was forgiving and used a temp stable powder. This one seems to do it all. Will run within 50fps a 7RUM and STW (same length barrels) with ALOT less powder.
