Its all a matter of cases. The short fat cases get better ignition and
more uniform velocities. B/r competitors regularly get 15 fps out of the
6 ppc and we got 7 to 15 out of our fat Mac 50( 20MM shortened and necked
to 50) Having said that, at ranges of 100 and 200 yards you
will be hard pressed to see a difference in group size at 100 fps spread
