Best set-up for chrono checks of .308 work-up loads.

Done my OCW work up for the Amax bullets. Chosen a load and an OAL.

I now want to do some target practice at 100m, but at the same time I'd like those to register on the chrono. A string of ten or so to get a good average velocity. I then want to use it to check trajectory in a BDC program.

What should I look at, look for, set up and account for so that those ten shots are neither inconclusive nor inaccurate?
And is there anything else the range time can tell me (aside from FPS) that I cannot get off the net but still need to make accurate trajectory calculations?
