If it were an improved 375-408 I'd say the following:
Its too big (350 grain pills are on the small end of too big
Its too fast (3250 or so is a bit much don't cha think?)
Its too flat (17 MOA come ups from 200 yd zero is a bit like bragging.
Its too accurate (clay birds at some very unreasonable distance is again like bragging.
It shoots too far (range finders get expensive to keep up with it.
Other than that its a pretty decent rig.
