Hornady list the b.c. at .550. I printed off a g7 ballistics table which said that it should take me 10.1 moa to get to 600 yards with a chrono'd speed of 2900 fps. When I shot yesterday, it took me 11.3. I went back in the program and it said the bullet would have to have a b.c. of around .450 for this to be true. Anybody ever shot these and if so how true did you find the b.c. to published. This was out of a 7rem mag with 67.6gr of h-1000.
