[QUOTE="Russ Hatch, post: 327609, member: 12444"] How large of a sample do you use for determining ES and SD, 5,10,15 or 20 rounds? Today I fired 18 rounds through the cronograph and had an ES of 56 and a SD of 14.5. All shots fired at the same aiming point with a group size of less than an inch. When looking at the read out from the Cronograph I noticed that the largest ES for three consecutive shots was 22 fps. So is this a good load or not? Russ [/QUOTE]
