CED if budget is a concern.
Lab Radar if not.
Some enterprising gunwriter could do a lot of good by using a labradar unit to test and publish negative acceleration rates for a range of projectiles.
Excluding wind it should be a fairly consistent number based on projectile size and shape. .
You mean actual real world ballistic coefficients.
Exactly but numbers with units in ft/s^2 (or ft/ms^2 is probably more useful) as opposed to a coefficent.
BC is a unitless coefficient. Right?
That would allow for an easy estimate of velocity or energy at distance X, Y and Z.
BuefordB,
That's why I figured a gunwriter could get a loan of one of the high dollar units...
If they tell you the time of each velocity measurement (or the delta between them) you can find the deacceleraton rate..
