The 200's I loaded in my 300 WSM got 2800 fps with decent accuracy. Three shots at 100 yards measured 1.17", at 200 yards 2.06". Call it 1 MOA.
Somewhere there is a link here where someone tested them in a 300 WBY at about 3000 fps. With impact speeds that fast they really came apart, but at 2700 fps performed as well as any other conventional bullet.
