If I were you, I would forget about the chrono as they are very, inaccurate.
Magneto speed is extremely accurate. If you don't know your speed you'll never be accurate at longer ranges.

What if you're "known" distances are off by 2%? Seems to me that it might be difficult to accurately measure 500 yards.

Seems to me that it might be difficult to accurately measure 500 yards.That, or a bunch of other factors like height over bore, zero, actual b.c., etc.If you're using advertised ballistic coefficient to calculate your velocity, your numbers are probably off a lot more than any chrono.
