Just for interestes sake:
Had Dad's .222 vixen out yesterday to shoot a fallow spiker and also tested some of my 6.5 loads (CM and PRC).
Put the magnetospeed on the vixen and fired 2 shots over it:
hornady 55gr SP over 21grs ar2207
1st 3185 fps
2nd 3184 fps.
Faster than we were expecting. Pretty fast for a .222rem! He had never chronied the load before but guessed it to be about 3000 fps max.
