[QUOTE="jabey9210, post: 824829, member: 24943"] If you go to jbm ballistics and input your numbers and change the "distance to chronograph" box to your distance it will show you your actual muzzle velocity on the trajectory chart if you look down to the drop chart you will see that at 0 yrds your muzzle velocity will be higher than what you put in because of the distance to chrono!!
