Thank you very much for the info. The improved case gives a increase of 10 grains of powder. The choice calibers was to try to get 3000 fps out of a 300 gr match king. I have found some posts on the 338 edge improved and my go with that. I am still in the information gathering stages of my project.

How can you get 10 more grains of powder in a 338 ultra improved? Thats more than the 338 Edge's powder increase (6 to 8) and it is a longer case, and there is minimal improvement to be had as James Jones pointed out.......
range it,check the wind, dial in correction, aim and only one shot
