Will do, I just saw your thread. I'm actually using .375 Rum brass to neck down and create a false shoulder for my .338 EDGE A.I. . I may just have to go with 300 RUM also. I am in dire need, Elk season is coming up and all my brass has 7 firings on it except for about 30 that have 6. If you find some let me know and I will do the same.
Good Luck.
