Simple, there's a significant chance that two round, fired back to back from the same revolver, can vary by a couple hundred fps.
Again, that does not show up in my experience, or on my chronograph; specifically when looking at .357 mag data.

My last outing that I measured with Buffalo Bore Heavy .357 mag in 180 grain had the following:
HI 1489
LO 1416
AV 1452
ES 73
Sd 51

Maybe your particular revolver has quite a difference in cylinder gap between those "two round".
