Ambient temperature and weather will make the velocities fluctuate from one day to the next, as will the small distance variations from the muzzle to the chronograph. View Quote View All Quotes View All Quotes Quote History Originally Posted By CTone03:

You could have a variation of 15 feet from the muzzle to the chronograph and that would only account for approximately 5 FPS difference in velocity for this load.
How many shots did you fire in a string when chronographing?
