Will 50fps make that much difference?
That is 50 fps at the muzzle with a different bullet. At 200 yards a GMX with a 50 fps head start will be closer to 200 fps faster than a Partition.
Don't know where you got that. According to my Oehler software, plugging in the stated velocities and the published BCs, at 200 yards the GMX would be running 2778 fps, while the Partition would be 2691fps. A difference of 87 fps, not 200!
Moreover, at 300 yds, the difference in trajectory would be less than 3/4". Why bother??
