The quick ones will slow down more rapidly than the slow ones due to the effect of (non-linear) increase in air resistance with increasing velocity; if the slow ones are also heavier (rather than just going slower due to variable energy input from the gun or frictional variations) then they may also have a slightly superior BC and hold more velocity that way too.

They are all going to end up at V=0 where consistency will be perfect!

BC at 50m was 0.0265 on average and the downrange velocity was actually more consistent than the muzzle velocity (curiously?)
