Chronograph Set Up On Home Loads....

I just received a small simple Chrony Chronograph and used it for the first time with some .38 special re-loads I just finished. All of these .38's were carefully prepared and I used a electronic weigh scale to get the powder at the same grains down to the same tenth of a grain but the results from the chronograph show some large variations in feet per second after shooting the rounds. In 25 rounds the fps ranged from 960-1209 with the vast majority around 975 feet per second. Are my re-loads that different, am I setting up the chronograph wrong, or are these cheaper chronographs that innacurate? I really don't know what I expected! Any tips would be appreciated...
